[TowerTalk] Triband tests

[Tom Rauch]

Hi Roger,

> Procedure for Antennas), page 101:

For the very same reason, a LONG test distance is also not 
recommended for horizontal antennas.

Moisture content, soil conductivity, and scattering all affect field 
strength since at a long distance the FS is actually being 
measured in a null caused by ground effects.
