Someone else might chime in here on this one but if I'm not mistaken
using the
coaxial cable in that fashion actually defeats the purpose as it should
be
terminated in its characteristic impedance at both ends to be effective.

I was going to try a variation of that, by putting the matching
transformer
at the long wire junction to the coax. We had a few warm days here, though
and the it's a mudhole back there, so I wait..



I seem to recall some effects of capacitance coming into play when used
as
you've described, and what happens there is that the coaxial cable is
simply
acting as a very long capacitor which might actually act as a block to
some
frequencies.

Possibly. If I ever get energetic I'll connect a signal generator to the
far
end and see what comes out on the radio side. I have an old scope here
that
will go to 30Mhz, so it should be fine. Things don't seem too bad now, but
I
have no way of knowing if they can get better until I try.



I'll have to look through the literature when I get a chance.
Depending upon how you have it hooked up you might not have noticed any
difference with a matching transformer if it was not attached properly.

Very true. I have no way of knowing to what degree the impedance
characteristics of the wire have been changed (if at all) by the single
point ground cable sheathing. That signal input test is starting to sound
better all the time.
