I have eight 130 foot elevated radials on my 160 meter Inverted L.
(about 65 ft vertical and the rest slopping down.) They are all 7-8 feet
above the ground. My antenna is in the woods so trees make a good
support for the radial wires. It seems to work for me since I usually
can work just about everything I hear when running the amp at about
800-900 watts.
