[Antennas] ground mounted vertical radials question

[Jim Miller]

Dave;

We suggest 60 1/4 wave length radials for each vertical to our 4-Square
and 2 element
phased vertical customers, for best results. If space does not provide
for 1/4 wave at 80 meters,
use 1/4 w length for 40 meters.
Try at least 20 radials & record resonant frequency.
Then add 10 more and compare results.
Continue until there are no changes, then you will sleep better knowing
you have provided
a very good ground return path for the 5BTV to work.

Good luck,
