e. Signal Power.
Your system should use the minimum amount of
power required for good reception and still overcome fading.
Low
power minimizes adjacent and co-channel interference within the
system.
It
also
reduces
interference
with
adjacent
or
interconnecting systems, and lessens the possibility of enemy
interception.
Using high-gain antennas achieves the same result as
increasing transmitter power.
f. Receiver Signal Power.
Using high gain antennas, properly
oriented, and situated away from noise sources provides better
reception.
Avoid local sources of interference to reduce noise.
Nearby communications equipment also generates interference and
increases the background noise level.
The receiver itself generates additional noise that the received
signal must compete with. Selecting high quality receivers, locating
them away from interference, using high gain antennas, and using
short, high quality transmission lines provides you the best possible
communications.

Tactical Applications.
Tactical multichannel radio equipment is highly versatile and
flexible.
No set rules control their application to tactical
communications.
However,
FM
100-5
does
require
certain
communications priorities. The signal plan designates the amount and
deployment of multichannel equipment.
This plan flows from the
signal planner's estimate of the situation.
Multichannel systems usually operate from point-to-point; that is,
from terminal to terminal, or when using relays, from terminal to
terminal through the relays.
a. System Configuration.
There are several factors that govern
the configuration, extent, and composition of multichannel systems.
Some of the mission, enemy, terrain, troops, and time available
(METT-T) factors are:
(1) Mission and basic organization for combat.
(2) Enemy capability.
(3) Terrain in the area of operations.
(4) Troops assigned for support by higher HQ.
(5) Time requirements.
(6) Location and movement plans of tactical and support units.
