These are not to be tuned radials. They will be ground mounted in the
grass. The antenna is a Butternut HV6V vertical. To simplify matters,
I will cut all the radials to 40 ft. which seems to be the about the
minimum length recommended for the lowest operating frequency, 80M.
Why are verticals such a PITA? I have dealt with yagis, quads, assorted
long wires, and Windoms with never this much trouble.
Years ago when I was a novice I used a Mosley RV-4. Ground mounted, no
radials, no nothing and never had a problem with it. I could work
anyone I could hear. I put the 80M loading coil on it, but worked
little 80M.
