Hi Chuck,
In general, with lousy ground, horizontally polarized antennas RULE!
The earth interacts with verticals in two ways. First, the soil under
the vertical is a big resistor, burning TX power. Second, where the
first reflection hits the earth (in the far field) reinforces the direct
So... if I am planning to move to the high desert of New Mexico in a few
years, what is the best low-band antenna option? I've used verticals over
lots of radials in Massachusetts and Mississippi with good success, but if
I'm up 6500 feet and the water table is WAY down there... what, a dipole?
Concurring with Tom, assuming you have the polarity of the X correct, and
there's more.
A short 1/4 wave-ish vertical that shows R=57 in the R+jX expression is a
vertical/counterpoise or radial(s) combo that has far too much resistance
and is a dead giveaway for a considerably inefficient antenna
Fred,
If your inverted 'L' was a bit less than a quarter wave long, it would have
been capacitive and showing 57-j130 (not plus). In which case you needed a
small inductor to match it to your 50 ohm coax, not a capacitor.
