The system of the present invention will accommodate two different polarity commands from two or more different sources at the same time. This satellite broadcast receiving and distribution system of the present invention will provide for the signals received from the satellite to be converted to standard frequencies so as to permit for signals to travel via existing wiring which the present day amplifiers can transport in buildings, high-rises, hospitals, and the like so that satellite broadcasting can be viewed by numerous individuals by way of a single satellite antenna.

BACKGROUND OF THE INVENTION 
1. Field of the Invention 
The present invention relates generally to a satellite broadcasting 
receiving and distribution system and more particularly to a broadcasting 
receiving and distribution system that will allow for the transmission of 
vertical and horizontal or left-hand circular and right-hand circular 
polarization signals to be transmitted simultaneously via a single coaxial 
cable. 
2. Description of the Prior Art 
Satellite broadcasting has become very popular throughout the United 
States. Conventionally, broadcast signals are transmitted through an 
artificial satellite at very high frequencies. These frequencies are 
generally amplified and are processed by a particular device after 
received by an antenna or antennas and prior to application to a 
conventional home television set or the like. 
Typically, broadcasting systems comprises an outdoor unit, generally 
associated with the antenna, and an indoor unit, generally associated with 
the television set, or the like. Both units, indoor and outdoor, are 
coupled via a coaxial cable. 
A problem associated with these types of systems is that they are designed 
to accept signals through a line of sight. Accordingly, if the satellite 
is not visual from a building, then the signal cannot be transmitted. 
Thus, these systems are rendered useless for high-rises, hospitals, 
schools, and the like. These systems are limited in usage, and, as such, 
can only be utilized in residential homes. 
As an example, U.S. Pat. No. 5,301,352, issued to Nakagawa et al. discloses 
a satellite broadcast receiving system. The system of Nakagawa et al. 
includes a plurality of antennas which, respectively, include a plurality 
of output terminals. A change-over divider is connected to the plurality 
of antennas and includes a plurality of output terminals. A plurality of 
receivers are attached to the change-over divider for selecting one of the 
antennas. Though this system does achieve one of its objects by providing 
for a simplified satellite system, it does, however, suffer a major 
short-coming by not providing a means of receiving satellite broadcasting 
for individuals who are not in the direct line of sight to the antennas. 
This system is silent to the means of simultaneously transmitting vertical 
and horizontal polarized signals via a single coaxial cable. 
U.S. Pat. No. 5,206,954, issued to Inoue et al. and U.S. Pat. No. 4,509,198 
issued to Nagatomi both disclose yet another satellite system that 
includes an outdoor unit that is connected to a channel selector. In this 
embodiment, the satellite signal receiving apparatus receives vertically 
and horizontally polarized radiation signals at the side of a receiving 
antenna. The signals are then transmitted, selectively, to provide for 
either one of the vertically or horizontally polarized signals to be 
transferred. Hence, utilizing a switch allow for only one polarity to be 
transmitted. This design and configuration provides for one coaxial cable 
to be utilized, but does not provide for the vertical and horizontal 
signals to be transmitted simultaneously. This system selectively 
transmits the desired signals and polarities. 
Systems have been attempted for transferring two frequencies on the same 
co-axial cable. Frequencies of the same polarity can easily be transmitted 
via a single co-axial cable, however, transmitting two signals, from two 
sources, each of different polarities can be a challenge. In some 
satellite configuration systems, once a timing diagram is plotted. For the 
signals to be transmitted, it is seen that a forbidden path occurs between 
frequencies of 950 MHz and 1070 MHz. Inherently prohibiting the 
frequencies within that range to be transmitted successfully. Hence, it is 
desirable to obtain a system which will not allow for conversion to occur 
at frequencies of the forbidden conversion. 
As seen in German Patent Number DE4126774-A1, signals can be fail within 
the range of the forbidden path, thereby, providing for a non-working 
system. Additionally, this product, like the assembly disclosed in 
Japanese Application No. 63-293399 both disclose a system which receives a 
single signal and demultiplexed them into vertical and horizontal 
polarized signals. These systems, are complex and require a numerous 
amount of components in order to employ the invention. This increase in 
components will inherently cause an increase in component failure. 
Further, these systems fail to disclose a means of reconverting the 
signals into their original frequency and polarity, a necessity for 
satellite systems. Consequently, the system provides a signal which will 
not maintain its respective polarity. 
Accordingly, it is seen that none of these previous efforts provide the 
benefits intended with the present invention, such as providing a 
broadcasting receiving and distribution system that will allow for the 
transmission of vertical and horizontal or left-hand circular and 
right-hand circular polarization signals to be transmitted successfully 
and simultaneously via a single coaxial cable. Additionally, prior 
techniques do not suggest the present inventive combination of component 
elements as disclosed and claimed herein. The present invention achieves 
its intended purposes, objectives and advantages over the prior art device 
through a new, useful and unobvious combination of component elements, 
which is simple to use, with the utilization of a minimum number of 
functioning parts, at a reasonable cost to manufacture, assemble, test and 
by employing only readily available material. 
SUMMARY OF THE INVENTION 
The present invention provides a satellite broadcast receiving and 
distribution system that will permit for the transmission of vertical and 
horizontal or left-hand circular and right-hand circular polarization 
signals simultaneously via a single coaxial cable. The system of the 
present invention will accommodate two different polarity commands from 
two or more different sources at the same time. This satellite broadcast 
receiving and distribution system of the present invention will provide 
for the signals received from the satellite to be converted to standard 
frequencies so as to permit for signals to travel via existing wiring 
which the present day amplifiers can transport in buildings, high-rises, 
hospitals, and the like, so that satellite broadcasting can be viewed by 
numerous individuals by way of a single satellite antenna. 
The satellite broadcast system of the present invention comprises a 
satellite antenna which receives the polarized signals, a head-in 
frequency processor for converting the polarized signals, a single 
co-axial cable for transmitting the converted signal, a head-out receiver 
processor for re-converting the signals to their original frequency and 
polarity, and a source, which receives the signals in their respective 
original frequency and polarity. Structurally, the head-in frequency 
processor is coupled to the head-out receiver processor via the single 
co-axial cable. The source is coupled to the head-out receiver processor. 
Hence, to allow for successful conversion, the head-in processor converts 
the received signals of two different polarities to frequencies which 
permit for transmission simultaneously. The head-in processor will also 
accommodate two different polarity commands from two or more different 
sources at the same time via the single cable. 
The single cable couples the head-in processor to the head-out processor. 
Once in the head-out processor, the signals are re-converted to their 
original state for transmission to the source (i.e. television). 
Accordingly, it is the object of the present invention to provide for a 
satellite broadcast receiving and distribution system which will overcome 
the deficiencies, shortcomings, and drawbacks of prior satellite broadcast 
systems and signals and polarity transfer methods. 
It is another object of the present invention to provide for a satellite 
broadcast receiving and distribution system that will convert different 
frequencies and different polarized signals in order to permit the signals 
to be transmitted via a single coaxial cable. 
Another object of the present invention is to provide for a satellite 
broadcast receiving and distribution system that will provide service to 
mid/high-rise office buildings, condominiums, schools, hospitals and the 
like via a single satellite. 
Still another object of the present invention, to be specifically 
enumerated herein, is to provide a satellite broadcast receiving and 
distribution system in accordance with the preceding objects and which 
will conform to conventional forms of manufacture, be of simple 
construction and easy to use so as to provide a system that would be 
economically feasible, long lasting and relatively trouble free in 
operation. 
Although there have been many inventions related to satellite broadcast 
receiving and distribution systems, none of the inventions have become 
sufficiently compact, low cost, and reliable enough to become commonly 
used. The present invention meets the requirements of the simplified 
design, compact size, low initial cost, low operating cost, ease of 
installation and maintainability, and minimal amount of training to 
successfully employ the invention. 
The foregoing has outlined some of the more pertinent objects of the 
invention. These objects should be construed to be merely illustrative of 
some of the more prominent features and application of the intended 
invention. Many other beneficial results can be obtained by applying the 
disclosed invention in a different manner or modifying the invention 
within the scope of the disclosure. Accordingly, a fuller understanding of 
the invention may be had by referring to the detailed description of the 
preferred embodiments in addition to the scope of the invention defined by 
the claims taken in conjunction with the accompanying drawings.

Similar reference numerals refer to similar parts throughout the several 
views of the drawings. 
DESCRIPTION OF THE PREFERRED EMBODIMENTS 
As illustrated in FIG. 1, the satellite system 10 of the present invention 
includes a receiving satellite 12 that will transmit signals 
(Vertical-polarized signals and Horizontal-polarized signals or left-hand 
circular and right-hand circular polarization signals) to a head-in 
equipment frequency processor 14. It is at this head-in equipment 
frequency processor 14 where the signals are received simultaneously and 
then transmitted via a single coaxial cable 16 to the head-out receiver 
processor 18. This will enable for the single coaxial cable 16 to transmit 
signals of two different polarities and frequencies simultaneously. From 
the head-out frequency processor the signals are reconverted to its 
original state and then transmitted to a source 20. As seen in FIG. 1, the 
two different polarities (Vertical-polarized signals and 
Horizontal-polarized signals or left-hand circular and right-hand circular 
polarization signals) are transported to the source via separate cables 
22a and 22b, respectively. 
The system of the present invention includes separate embodiments, and the 
first embodiment is illustrated in FIG. 2. As seen in the first embodiment 
of the present invention 10a, there is shown a head-in frequency processor 
14a couple to either a first head-out frequency processor 18a or a second 
head-out frequency processor 18b. 
It is noted that FIG. 2 illustrates the head-in processor 14a to be coupled 
to two separate head-out processors 18a and 18b, respectively. This is 
shown for illustrative purposes only. In actuality, only one head-out 
receiver processor is utilized with the head-in processor 14a. The type 
and embodiment used for the head-out receiver processor is dependent to 
the combination of the satellite receiver and source that is utilized. 
As seen in FIG. 2, the head-in equipment frequency processor 14a will 
receive two signals or two separate polarities and convert them to 
separate frequencies for enabling transmission via a single coaxial cable 
16a. 
A low-noise block converter (LNB) 24 will receive the signals from the 
satellite 12. This LNB 24 is conventional and is used for amplifying the 
respective polarized signals (Vertical-polarized signals and 
Horizontal-polarized signals or left-hand circular and right-hand circular 
polarization signals). Accordingly, after signals are received, they pass 
the low-noise block converter 24, to provide for the signals to enter the 
head-in equipment frequency processor 14a (illustrated in FIG. 2 as dashed 
lines) via conduits 26a and 26b, respectively. 
The head-in equipment frequency processor 14a, illustrated in FIG. 2, 
provides for the signals to be converted, via converters 28 and 30, to the 
frequencies which the present day amplifiers can transport. In this stage 
of the system, the object is to convert the signals of one polarity up 
(via converter 30) and to convert the signals of second polarity down (via 
converter 28). This will render the converted signals to be transmitted 
without emerging into the forbidden frequency conversion. 
From the conduits 26a and 26b, the signals are transmitted to a first 
converter or down converter 28 and a second converter or up converter 30. 
These frequency converters, 28 and 30, respectively, convert the entered 
frequencies to a frequency which present day amplifies can transport. The 
converters will be discussed in further detail in FIGS. 3a and 3b. The 
utilization of two converters permit for the acceptance of two signals or 
polarized transponders that are of a different frequency. 
In the down converting means 28, the transponder is converted down to a 
specified frequency. The specified frequency is the frequency that is 
required for the present day amplifiers for transportation. The newly 
converted frequencies are amplified through the amplifying means 32a. At 
means 32a, the converted frequencies are amplified so not to create second 
harmonics. These signals are then transferred to a conventional four way 
splitter 34a. 
In the up converting means 30, the transponders are converted up to a 
specified frequency. The converted frequencies then are converted down via 
a down converter 36. This process of converting up and then down provides 
for frequencies to be converted without difficulties and avoiding the 
forbidden conversion area. 
The convert ed signals are transferred to the four way splitter 34a in 
ordered to combine the frequency of the amplified signal of 32a and 
frequency from converter 36. To synchronized the system, the frequencies 
from the phase lock loop (PLL) transmitter 38a are transmitted to the 
splitter 34a. 
From the splitter 34a, the signals are passed through an AC power separator 
40 which routes 60 Volts power to a DC power supply of 18 Volts. This will 
permit for the dual frequencies from the satellite dish 12 to be 
transmitted simultaneously via a single coaxial cable 16a. Dependent upon 
the length of the cable, an optional conventional amplifier 42 can be 
coupled thereto. Power from a power source 44 is inserted into the lines 
via a power inserter 46. The signals are amplified, as needed, with 
additional amplifiers 48. It is noted that the amplifiers are optional and 
are dependent to the distance that the head-in frequency processor 14a is 
located from the head-out frequency processor 18a or 18b. The power supply 
and power source 11 en energizes the head-in frequency processor 14a. 
From the single coaxial cable 16a, the signals are adjusted via a tap 50a 
to permit for the appropriate decibels that are required for the head-out 
processor 18a or 18b. 
The head-out frequency processor used for the head-in processor 14a 
illustrated in FIG. 1, can include two embodiments, dependent upon the 
embodiment for the source in combination with the satellite receiver. 
The first embodiment for the head-out frequency processor is illustrated in 
FIG. 2 by way of dash line 18a. As seen in this embodiment, the 
simultaneously transmitted signals enter the processor via conduit 16b. 
The conduit 16b is coupled to a conventional four (4) way splitter 34b. A 
conventional phase lock loop (PLL) receiver 56a is coupled to the splitter 
34b to permit for the signals to be locked to the proper and desired 
frequencies. From the splitter 34b the first frequency is transmitted to a 
first converter 58a in order to permit for the signals or transponders to 
be converted up to a specified frequency. This up converted signal from 
the first converter or up converter 58a is then transmitted to the 
satellite receiver by way of a conduit 22b. 
The second frequencies are transmitted to a first or up converter 52a and 
then are transported to a second or down converter 54a. This will permit 
for the signals to be converted to the desired frequency. This second or 
down converter is coupled to the satellite receiver 21 via conduit 22a. 
The signals from down converter 54a and from up converter 58a are in the 
original state, both frequency and polarity, when transmitted from the 
satellite to the head-in processor 14a, via lines 26a and 26b. The 
re-converted signals, frequencies and polarity in its original state, are 
transmitted to the satellite receiver 21 via lines 22a and 22b. The 
satellite receiver 21 is coupled to a source 20 (illustrated as a 
television) to provide for proper transmission of the signals. The 
transmission line between the satellite receiver 21 and source 20 is 
illustrated but not labeled. 
Hence, it is seen that the head-in processor converted the signals to 
different frequencies to enable the transmission of two separate polarized 
signals via a single co-axial cable to a head-out processor. From the 
head-out processor, the signals are re-converted to their original state, 
which was received via lines 26a and 26b. For example, with satellite 
systems, frequencies typically range between 950-1450 MHz. If the 
satellite transmits a frequency of 1450 for both the horizontal and 
vertical polarities, then one of the polarities, such as horizontal, is 
converted down to 560 MHz via converter 28. The second frequency of the 
second polarity, such as vertical, is first converted up to 2010 and then 
back down to 1070, via converters 30 and 36, respectively. Such a 
conversion allows for the two frequencies of two different polarities, 560 
MHz (horizontal) and 1070 MHz (vertical), to be transmitted simultaneously 
on a single co-axial cable (16a and 16b). 
As illustrated, this head-out frequency processor is the reverse process of 
the head-in processor. This is to provide for the signals to reconverted 
to its original frequencies so as to provide for the satellite receiver 21 
and source 20 to accept the signals. The single cable 16b accepts the 
signals at frequencies different than that of the source. Accordingly, the 
head-out processor must re-convert the signals to the frequencies that are 
utilized by the source 20. 
An alteration of the satellite receiver requires an alteration in the 
head-out receiver processor. This alteration is illustrated in FIG. 2 and 
is shown in outline designated as reference 18b. In this design and 
configuration, the satellite receiver utilizes only one wire and accepts 
only one type of signal, selectively, such as only left-hand circular or 
only right hand circular polarized signals. 
As seen, the frequencies are tapped via 50b. The tap 50b is coupled to the 
head-out processor 18b via line 16b which is connected to a four (4) way 
splitter 34c. To provide for the signals to be locked in proper 
frequencies, the four way splitter is coupled to a phase lock loop (PLL) 
receiver 56b. 
From the splitter 34c, the first signal of a first polarity is transmitted 
to a first or up converted 52b and then is transmitted to a second or down 
converter 54b. The conversion of the signals from up to down provides the 
benefit of converting the frequency without any mishap or error. This 
method of conversion will avoid the forbidden conversion area as well as 
provide for the original received frequency and polarity of the signals. 
The signals of the second frequency and second polarity are transmitted to 
an up converter 58b which will inherently convert the signals to its 
original received frequency while maintaining its polarity. A polarity 
switch 60 is connected to converters 52b, 54b, and 58b for coupling the 
head-out processor to the satellite receiver via a single cable 22c and a 
joining means, which is a four way splitter 34d. The satellite receiver 21 
is connected by way of a line (illustrated, but not labeled) to a source 
20. In this embodiment, the switch 60 is used to determine which polarity 
will enter into the head-out processor 18b. 
In the embodiments shown above, the satellite receiver 21 and source 20 are 
conventional components and as such, their schematics are not shown in 
further detail. The up and down converters used in the embodiment above 
will be discussed in further detail in FIG. 3a and FIG. 3b. FIG. 3a 
represents the schematic rendering of the down converters (28, 36, 54a, 
and 54b) and FIG. 3b represents the schematic rendering of the up 
converters (30, 52a, 52b, 58a, and 56b). 
As seen in the schematic diagram of FIG. 3a, the signal enters the down 
converter via line L1. The entered signal passes through a first capacitor 
C1 which is coupled to an amplifier AMP. After passing the amplifier AMP, 
the signal passes a second capacitor C2 before entering a first low pass 
filter LPF1. This first LPF1 is coupled to a mixer which is coupled to a 
second LPF2. This second LPF2 is connected to a third capacitor C3 which 
is coupled to a second choke CH2. The mixer is also connected to an 
oscillator OSC. The oscillator is coupled to a PPL. The first capacitor C1 
is also connect to a first choke CH1. Capacitors C, C1, C2, C3 are coupled 
to the amplifier, oscillator, phase lock lope PPL, and the second low pass 
filter. Resistors R are coupled to the amplifier, oscillator, first low 
pass filter and mixer. Chokes are also coupled in series with capacitors 
to provide for the chokes to be parallel with the amplifier AMP and the 
second low pass filter, respectively. As seen the chokes CH1 and CH2 
(inductors) and capacitors C are a DC bypass filter network and provide a 
DC path and enables passing DC power to the antenna electronics. 
The up converter is disclosed in FIG. 3b. As seen in this drawings, the 
signal enters the up converter via a first line L2. The converter further 
includes an amplifier AMP that is coupled to a first low pass filter LP1. 
The amplifier is also coupled to an oscillator OSC. The oscillator and the 
first low pass filter are connect to a mixer. This mixer is coupled to a 
high pass filter HPF. The oscillator is also connected with a phase lock 
loop receiver PLL. A second amplifier AMP2 is coupled to the high pass 
filter HPF. A second low pass filter LPF2 is coupled to the second 
amplifier. Capacitors are coupled to the first amplifier, first lower pass 
filter, and a the amplifier. Resistors R are coupled other first and 
second amplifiers, oscillator, first low pass filter, and mixer. Chokes 
are also used in this circuit. The first choke is coupled to a capacitor 
which is coupled to the first amplifier. The second chock is coupled to 
the phase lock loop. 
Simplifying the head out processor described above, will provide another 
embodiment for the satellite broadcast receiving and distribution system. 
This system is illustrated in further detail in FIG. 4. This embodiment 
simplifies the above describe embodiments and also provides a device which 
avoids the forbidden path. Alteration for this embodiment occurs in the 
head-in equipment frequency processor 14b and the head-out frequency 
processor 18c. 
As with the first embodiment, a low-noise block converter (LNB) 24 will 
receive the signals from the satellite 12. This LNB 24, as stated 
previously, is conventional and is used for amplifying the respective 
polarized signals (Vertical-polarized signals and Horizontal-polarized 
signals or left-hand circular and right-hand circular polarization 
signals). Hence, after signals are received, they pass the low-noise block 
converter 24, to provide for the signals to enter the head-in equipment 
frequency processor 14b (illustrated in FIG. 4 as dashed lines) via 
conduits 26a and 26b, respectively. 
The head-in equipment frequency processor 14b, provides for the signals to 
be converted, via converters 28 and 30, as identified for the first 
embodiment. Thereby providing a system which includes frequencies that the 
present day amplifiers can transport. In this stage of the system, the 
object is to convert the signals of one polarity up (via converter 30) and 
to convert the signals of second polarization down (via converter 28). 
From the conduits 26a and 26b, the signals are transmitted to a first 
converter or down converter 28 and a second converter or up converter 30. 
These frequency converters, 28 and 30, respectively, convert the entered 
frequencies to a frequency which present day amplifies can transport. The 
converters have been discussed in further detail in FIGS. 3a and 3b. The 
utilization of two converters permit for the acceptance of two signals or 
polarized transponders that are of a different frequency. 
In the down converting means 28, the transponder is converted down to a 
specified frequency. The specified frequency is the frequency that is 
required for the present day amplifiers for transportation. Though not 
illustrated, the newly converted frequencies are amplified through the 
amplifying means, as illustrated in FIG. 2 via element 32a. At the 
amplifying means 32, the converted frequencies are amplified so not to 
create second harmonics. These signals are then transferred to a 
conventional two-way splitter 34c. 
In the up converting means 30, the transponders are converted up to a 
specified frequency. The converted signals are transferred to the two way 
splitter 34c in order to combine the frequency of the amplified signals. 
To synchronized the system, the frequencies from the phase lock loop (PLL) 
transmitter 38a are transmitted to the splitter 34c. 
From the splitter 34c, the signals are passed through a conventional tilt 
and gain 62. This will permit for the dual frequencies from the satellite 
dish 12 to be transmitted simultaneously via a single coaxial cable 16a. 
Dependent upon the length of the cable, an optional conventional amplifier 
42 can be coupled thereto. Power from a power source 44 is inserted into 
the lines via a power inserter 46. The signals are amplified, as needed, 
with additional amplifiers 48. It is noted that the amplifiers are 
optional and are dependent to the distance that the head-in frequency 
processor 14b is located from the head-out frequency processor 18c. The 
power supply and power source 11 energize the head-in frequency processor 
14b. 
From the single coaxial cable 16a, the signals are adjusted via a tap 50a 
to permit for the appropriate decibels that are required for the head-out 
processor 18c. 
The head-out frequency processor used for the head-in processor 14b is 
illustrated in by way of dash line 18c. As seen in this embodiment, the 
simultaneously transmitted signals enter the processor via conduit 16b. 
The conduit 16b is coupled to a conventional two (2) way splitter 34d. A 
conventional phase lock loop (PLL) receiver 56a is coupled to the splitter 
34d to permit for the signals to be locked to the proper and desired 
frequencies. From the splitter 34d the first frequency is transmitted to a 
first converter 52c in order to permit for the signals or transponders to 
be converted up to a specified frequency. The converted signals from the 
first converter or up converter 52c are then transmitted to the satellite 
receiver by way of a conduit 22a. 
The second frequencies are transmitted to a down converter 54c. This will 
permit for the signals to be converted to the desired frequency. This 
second or down converter is coupled to the satellite receiver 21 via 
conduit 22b. The signals from down converter 54c and from up converter 52c 
are in the original state, both frequency and polarity, when transmitted 
from the satellite to the head-in processor 14b, via lines 26a and 26b. 
The re-converted signals, frequencies and polarity in its original state, 
are transmitted to the satellite receiver 21 via lines 22a and 22b. The 
satellite receiver 21 is coupled to a source 20 (illustrated as a 
television) to provide for proper transmission of the signals. The 
transmission line between the satellite receiver 21 and source 20 is 
illustrated but not labeled. 
Hence, it is seen that the head-in processor converted the signals to 
different frequencies to enable the transmission of two separate polarized 
signals via a single co-axial cable to a head-out processor. From the 
head-out processor, the signals are re-converted to their original state, 
which was received via lines 26a and 26b. The above identified embodiment 
is ideal for long distant use, i.e. exceeding 1000 feet. However, for 
shorter distance, i.e. less than 1000 feet, the components can be 
simplified again to provide for a device which is ideal for use in 
apartments or the like. 
As seen in FIG. 5, the present invention includes the head-in equipment 
frequency processor 14c and the head-out frequency processor 18d. 
As with the first the previous embodiments, a low-noise block converter 
(LNB) 24 will receive the signals from the satellite 12. This LNB 24, as 
stated previously, is conventional and is used for amplifying the 
respective polarized signals (Vertical-polarized signals and 
Horizontal-polarized signals or left-hand circular and right-hand circular 
polarization signals). Hence, after signals are received, they pass the 
low-noise block converter 24, to provide for the signals to enter the 
head-in equipment frequency processor 14c (illustrated in FIG. 5 as dashed 
lines) via conduits 26a and 26b, respectively. 
As seen, this head-in equipment frequency processor 14c is simplified. The 
head-in equipment frequency processor 14c, provides for signals of one 
frequency to be converted, up via converter 30, as identified for the 
first embodiment. Thereby providing a system which includes frequencies 
that the present day amplifiers can transport. In this stage of the 
system, the object is to convert the signals of one polarity up (via 
converter 30). The signal of the second polarity is amplified via 
conventional amplifier 32a. 
From the conduits 26a and 26b, the signals are transmitted to a first 
converter or up converter 30 and a amplifier 32a. The down converters have 
been discussed in further detail in FIG. 3a. 
From the amplifier and up converter, the signals are transferred to a 
conventional hybrid mixer 36a. From the mixer, the signals pass a diplexer 
64. Signifies exit the diplexer via a single co-axial cable 16a. 
From the single coaxial cable 16a, the signals can be adjusted via a tap 
(illustrated, but not labeled) to permit for the appropriate decibels that 
are required for the head-out processor 18d. 
The head-out frequency processor used for the head-in processor 14c is 
illustrated in by way of dash line 18d. As seen in this embodiment, the 
simultaneously transmitted signals enter the processor via conduit 16b. 
The conduit 16b is coupled to a conventional mixer 36b. From the mixer 36b 
the first frequency is transmitted to an amplifier 32b and the second 
frequency of a different polarity is transferred to a down converter 52d 
for converting the frequency to its original state. 
The re-converted signals, frequencies and polarity in its original state, 
is transmitted to the satellite receiver 21 via lines 22a and 22b. The 
satellite receiver 21 is coupled to a source 20 (illustrated as a 
television) to provide for proper transmission of the signals. The 
transmission line between the satellite receiver 21 and source 20 is 
illustrated but not labeled. 
Hence, it is seen that the head-in processor converted the signals to 
different frequency to enable the transmission of two separate polarized 
signals via a single co-axial cable to a head-out processor. From the 
head-out processor, the signals are re-converted to their original state, 
which was received via lines 26a and 26b. The above 
The satellite system of the present invention will permit for two signals 
of different frequency and polarities to travel simultaneously via a 
single coaxial cable. The use of this will provide for a satellite system 
that is versatile, economical and compact. The usage of the single cable 
permits for a system that can accept satellite broadcasting in places that 
were previously render impossible. These places include mid/high-rise 
office buildings, condominiums, hospitals, schools, etc. The unique design 
and configuration enables the signals to be transmitted via the existing 
wiring of the buildings. The only renovations that may need to be done is 
the upgrading of the existing amplifiers. 
While the invention has been particularly shown and described with 
reference to an embodiment thereof, it will be understood by those skilled 
in the art that various changes in form and detail may be made without 
departing from the spirit and scope of the invention.
