PERFORMANCE MEASURE 2
DETERMINE SUPPORT REQUIREMENTS
The use of terrain masking, one of the greatest defenses against enemy
interception of your radio transmissions, is denying him the knowledge that you
are transmitting at all. The most effective way to accomplish this is through
the use of directional antennas and "terrain masking."
a. Directional antennas place most of the signal strength in only one or
two directions. By proper orientation of the antenna, most of your radiation
will be away from the enemy and to the person(s) to whom you want to talk.
to be established broad side to the antenna. (See figure 7 below.)
c. Unfortunately, sometimes correctly orienting your antenna to talk to a
rear station causes the other side to radiate into enemy held territory. Here
is where terrain masking must be used.
