[Elecraft] Inverted-L (was OT: Vertical antenna)

[Don Wilhelm]

  Guy,

I know it is not equal to your statements, but in my mind you are making 
a good case for the use of elevated (and tuned) radials.  L B Cebik 
recommended them to me at FDIM several years ago over in-ground radials 
and I have never done the work of burying the radials, so I have no 
comparison.  Mine are supported on electric fence insulators in the 
trees 10 feet up, and the monopole and radials are tuned together using 
the techniques outlined in UN4ON's Low-Band DXing (page 9-23).
The radiator is the 40/80 vertical/160 inverted L BC-Trapper also 
described in the same book. (yes, I have radials for 40 and for 80 and 
for 160).

It works well for me, and no way did I want to dig through the tree 
roots in the forest nor trip over wires on the ground when I wanted to 
take a walk.

There are good reports of elevated radials, although some measurements 
by Tom Rauch W8JI indicated some disagreement, but for my situation it 
is the best solution despite any controversy.

73,
Don W3FPR
