The first sensible question.

"Radials and Counterpoises have two basic purposes:
1. To improve the RF ground conductivity for the ground current return path.
Unless you live in a salt-water swamp, your ground conductivity makes a very
poor path for the return of ground currents. This increases the ground
losses and reduces the efficiency of an antenna that needs a good RF ground.

E. More radial wires are generally better. As the number gets larger, they
improve the RF Ground less and less, to the point where there is no
difference when adding one more radial to a system that already has 120
installed. Minimum systems of as few as 4 wires can provide an acceptable
ground and increase the antenna's efficiency by a significant amount.
Generally, 6-8 radials is the minimum that should be used." From:

If you believe ANYTHING that was published by SGC, you need to go back
to school and relearn everything you ever thought you knew about RF
Antenna Systems. There is a reason Don Stoner, left the company decades
ago, and PeeAir couldn't design his way out of a Wet Paper Bag.


As you see in the radials are many ends. There is the lower voltage and
almost no radiation (electron loss). Radial work like the receiver antena
(caught electrons from air)

Without the radials your stations can work only in a "salt-water swamp".
