it. QED

Length (feet) = (984*(N-0.025)) / Freq (Mhz)

where N is the number of full waves on the antenna.  Thus, 
a 2 wavelength antenna at 15 Mhz would be:

984*(2-0.025)/15 = 129.56 feet.  The gain of the
longwire antenna varies more or less linearly with
the number of wavelenghts long it is; the longer the
antenna wire, the better.  Longwire antennas are 
directional; the longer they are, the more directional.
Maximum gain is along the direction of the length of
the wire.  A longwire 4 wavelengths long has twice
the gain of a dipole.  Care must be used in matching
the longwire to the antenna; a tuner is frequently
needed.  As always, a lightning arrestor is a must.

Subject: question on phone antenna
Organization: HAC - Johns Hopkins University, Baltimore
Date: Mon, 14 Dec 1992 15:57:44 GMT

Hello,
I have a few questions regarding the construction of
an antenna using a phone wire as posted by someone
on the net.

1) Why do we use passive filters? and not active?

This question popped up when I found that RadioShack
does not store inductors. We can build filters with
the same characteristics using Op Amps and capacitors
alone. Why do we not do that?

2)Why is the filter symmetric? i.e why do we have 
something like

3) Is it possible to build tuning circuits also with
active elements and capacitors alone? If yes,
why don't people do so?

Thanks for your time,
Answers will be appreciated, and I will post the summary
of results later

Babu

You can make your own inductors easily.  The ARRL handbook, among others,
tells how.

No particular reason that I can think of, except that both ports are the same
and are therefore interchangeable.

It is possible, but op-amps that have significant gain at 30 MHz are
expensive and add to the noise and distortion of the signal.  Active filters
are primarily useful at audio frequencies where large inductors would be
required.

I just recently got my old National NC109 repaired. There's nothing 
like searching the broadcast bands with an analog slide rule tuning
dial, where if you bump the knob, you slide by 30 stations (the
band spread dial cord is broken). It's so much more fun searching
for interesting sounds when you have no idea what frequency you
are listening to (plus or minus 100khz). It is a sinch to find
the stronger stations on, and a challange to tune in the weak ones.
I own a NRD-515, and DX440, but for general tuning around, I perfer
the old national. My friend feels the same way. He made the comment,
"they should put slide rule dials on modern PLL recievers".

   You have probably changed the directionality of your
antenna, so that some higher frequency stations became
weaker, but others, in different directions, may be stronger.
   Also the impedance of the antenna at the input to your
receiver will vary with frequency, so that the long antenna
may be giving lower voltage to your receiver at some narrow
bands on the higher frequencies.  The capacitor to affect
the impedance at the higher frequencies will have a particular
value at a particular frequency.
    The impedance problem can be dealt with, at the cost of
inconvenience, with an antenna tuner, a number of which are
sold by various suppliers.  MFJ and Palomar are leading US
ones.  The inconvenience is that you will have two or more
adjustments to make for each new band of frequencies you
tune.  Simple antenna matching devices are a variable induct-
ance in series with a variable capacitor connected from 
antenna to ground (or earth, depending on which variety of
English you speak) with the receiver input connected from
ground to the connection between the two components.  The
matcher will be variously effective with the capacitor at
the grounded end and with the inductor at the grounded end.
   See ARRL handbook or various antenna books in a library.
Good luck!

>Which one do you prefer and why?

Well, my opinion on this is posted in the monthly intro article, but
in brief, there are essentially two ways to tune around the dial:
bandscanning, where you tune at random and mark what you find, or
pinpoint, where you decide what you want to listen to and then find
it.  Passport is aimed at the first mode, and the WRTH at the
second.  However, Passport makes no effort to be a comprehensive
reference for pinpoint listening, so it is not very useful in that
mode.  The WRTH, on the other hand, contains a listing by frequency
in the back of the book that can be used for bandscanning, with a
little effort in cross-referencing.  I used it that way for years
before Passport came along.  So if I could only have one,
the WRTH would be the one I would pick hands down.

This does not take into account Passport's good articles for beginners
which attempt to demystify "world band" radio, or their new feature
rating QSLing performance of stations, or their excellent receiver
review section, or the WRTH's feature articles and receiver reviews
and interest in computers.  These are all nice, but they're not the
reasons I buy the books.

Now what I really want is a CD-ROM that combines the
comprehensiveness of the WRTH's listings with the ability to view in
a Passport-type format if desired and the ability to control
high-end receivers of Tom Sundstrom's PC programs or Jim Frimmel's
Shortwave Navigator for the Macintosh, and the possibility of
downloading periodic updates, and lots of articles like those in
Passport and maybe full text of some club bulletins.  I'm not asking
for much, am I?  :-)

But they could simply use an automatic reply with a form letter, ensuring
prompt automatic responses:

Dear Kim [klg@orion.mc.duke.edu],

Thank you for your interest in the BBC and your fascinating e-mail.
Everyone here is pleased to know you took the time to write as you did.

                                                Kind regards,
                                                Marmaduke Hussey
                                                Director General

                                       mh@autoreply.ws.bbc.com.uk

Then later someone would read your e-mail to see if any action is
necessary, sending a programme schedule, noting a transmission
report, dealing with an IRA bomb in the corridor, whatever you were
writing about.

[Marmaduke Hussey is just a silly name that came into my head, he is
unlikely to be the DG now, probably never was. May be a BBC1 comedy
character for all I know...]

When using older radios to receive SSB it helps if the radio has an
RF gain control.  Without it, a strong signal can sound distorted.
Reducing the gain can improve reception.  The reason for this is due
to that fact that older radios don't have "Product detectors" (A circuit
that was designed for SSB reception).

I think that the BFO is normally set to the IF of 455KHz which is fixed. 
Isn't it?
