Jeff-

I doubt that the linearly loaded antenna, which is in fact an inductively
loaded antenna, would have less radiated power loss in general.

Radio energy is radiated from the current flowing in the antenna, as
opposed to the voltage.  Current is higher at the low impedance points,
such as the center of a half wave dipole, dropping to zero at the end of
the antenna.  As a rule of thumb, 2/3 of the radiation is from the central
third of a half wave dipole, or the bottom third of a quarter wave
groundplane.

It would be best for effeciency, to have the inductive loading as close to
the end as practical.  By doing so, the portion of the antenna that has
high RF current, is maximumized.  The drawback is that the antenna
bandwidth becomes narrower, as you move the loading toward the end.  If you
place the loading coil near the high current point, the current flowing in
the coil does not radiate much, and burns up some of your power in the
resistance of the wire.

A continuously loaded antenna will probably have a wider bandwidth than an
end-loaded antenna, and not have as much power loss as an antenna with
loading concentrated at a high current point.

As far as popularity, I recall seeing advertisements for linearly loaded
fiberglass CB mobile antennas, as well as a "Slinky" halfwave dipole for
hams.  However, that's about it.  They probably cost more to make, or
something!

well i agree with everybody who says the law is confusing but arent most of
them anyway i for one know that if you have a transceiver or transmitter
type radio that it is illegal to carry it around until you get licensed
and if a police officer catches you with one and knows you arent licensed
then they can confiscate it and possibly arrest you i know this from first
hand experience [had run in about this topic with one of the campus police
here]

well dont know if i ckarified anything or made even more misty but i tried
to clarify it as bnast as i can

No, I don't have any affiliation with, nor any particular allegiance to,
Jun's electronics, though I do know one or two of the employees there
from club affiliations outside work (the same is true, BTW, of Henry
Radio and HRO).  I've done a fair amount of business there because it's
relatively close to my home and has reasonable prices.  They've screwed
things up royally once or twice, and gone out of their way to help me
more often than that.

Since I stop by often enough as it is, there was no question of "taking
the time to go to all that trouble".  I acted, as I said, more or less from
the feeling that an attack to which the accused cannot respond is not
taking place on a level playing field.

Jun's, BTW, has decided not to respond further to the current thread,
though I provide copies of all messages in the thread to them.

The whining is about the code requirement.  I'm not asking for
a multi-media band below 30MHz.  Would you require expertise
in AtoD, DtoA, DSP and other digital methods to operate ABOVE 30 MHz?
Probably not.  So why the code requirement BELOW 30 MHz?

Why stop at code?  Prior to that, we had the pony express!
Why not require all hams to pass a test on riding a horse?

The point is that some "traditions" belong in the history books.
If you want to use them, fine.  But making them a requirement
sacrifices time that could have been better spent learning
newer technologies.  THAT IS WHAT WILL ADVANCE HAM RADIO!

The Thai King (Bhumibol Adulayadej [sp?]; born in W1-land) is often

Now, would a died-in-the-wool CW nut be caught with a rig that has a

In the last few years, the population of no-Morris Hams has exploded
in HS-land.  H. M. King is very popular in said country, helping

I got the AN980 Application note from Motorola for the MC3362,3 and it has
schematics for building a 2 meter FM receiver. But what got me really
interested was the two internal oscillators and mixers that are in 
the chip. Looks a easy way to build a Superhet as all you would have
to do use one for the local oscillator and the other for the beat freq
oscillator and then put a 9mhz or 455 mhz filter between the two and bingo
a Superhet! As I want to build a 10 meter receiver for working the RS-12
it looks a cheap and easy way to do it. This chip was used in a construction
article a while back but for the life of me I can't remember what magazine
it was. Anyone remember what issue and mag it was? As the oscillator 
is designed for a lot higher freq's it should work great for 10 meters
and 6 meters. Has anyone done any work with this chip? 73!

      In the beginning was King Spark.  "Continuous waves" came later.

      It's amusing to see microprocessor-controlled, frequency-synthized,
digital-readout rigs being used for CW.  It's like retrofitting a Model

I've always heard that folded dipole made for 300 ohm twin lead and fed with 
50 ohm coax and the height adjusted until the swr was 1 to 1 worked well for
local contacts. 

What you are making is a two element close spaced yagi and taking advantage 
of the lowering of the feed point impedance due to the closeness of  the 
reflector. 

I have also seen this as a inverted vee with the reflector below the folded  
element. I am not sure but as I recall the reflector should be 0.18 wave
lengths below the driven element and 105% longer than the driven element.
