[Hallicrafters] Advice sought on antenna cable type

[Glen Zook]

At 40 meters the loss in the feedline is basically nil
(I know, there is always some, the most with RG58/U of
the types mentioned, but for all practical purposes it
can be ignored at 7 MHz).

Now, if he is only interested in 40 meter operation,
then he will be better off using coax since this will
not require an additional piece of equipment (namely
an "antenna tuner") in his shack.  An antenna tuner
requires a "bit" of tuning and adds to the complexity
of the the installation.

If he is interested in adding 20 and 10 (15 meters
will work automatically on a 40 meter dipole), then it
would be cheaper just to add wires for 20 and 10
meters in parallel with the 40 meter arrangement
("parallel" or "fan" dipole).  Those antennas work
fine and are still fed directly with coax which
matches the output impedance of the HT-37, thus,
eliminating the need for an antenna tuner.  Around $5
for the wire if he doesn't have it around!

With the HT-37 you don't have to worry about the WARC
bands or the new 60 meter band.  It doesn't work
there!

Put up the longest piece of wire you can, feed it in
the center with open-wire line, use a truly balanced
antenna tuner, then load up on any band.
