I always resorted to "that looks about right" and it usually works<:-)) at
least for radials. I am going to have to try a set under the Hy-Gain AV-640
which supposedly doesn't require radials when ground mounted. Mine's at 32'.
It works well on all bands except 20 where it appears to be deaf. SWR is
good, but I hear few stations and even running the legal limit few hear me.
Which is another reason for wanting to set it up so I can switch to the
antennas on the big tower.
