[TowerTalk] Vertical with 1 radial

[Gary Schafer]

The question is "gain over what"? 

Gain over a vertical with 36 radials? I wouldn't think so!

3 dB of gain in the direction of the radial over the gain in the opposite
direction? Possibly. Even though the whole thing may be down 6 or 8 db over
a vertical with a large number of radials.
