Subject: Sigma-5
Author: Lloyd A. Bartlett <lloydbartlett@earthlink.net>
Date: 28-Apr-2002 10:53:23
Force 12 states : "SIGMA-5 efficiency is independent of the ground. To
enhance the low angle energy, one can add an extensive ground screen (dense
for 20-30') under the antenna (then more screen or wires out to perhaps 5
wavelengths)."
I would like to hear from those who do, and those who don't use ground
systems with Sigma-5.

Lloyd, K7CIX
