[TowerTalk] vertical antennas

[Rajiv Dewan, N2RD]

An early adopter of Force 12's 160VX (56' tall, linearly loaded vertical for
the 160 band) told me that after one season of 4 elevated radials, he
installed an extensive ground radial system.  It improved the antenna
considerably.  Some one he has skeds with asked him what he had done to get
so much louder.

I do not have any more details.  I filed this information in my brain for
when I try to do the same.

Regards,
Rajiv, N2RD
