1.
B.
300-3500 Hz.
Each piece of equipment operates over a designed bandwidth.
Often there is more than one band over which a piece of
equipment operates.
You find this designed feature, along
with other technical characteristics, following the equipment
description, or in the applicable technical manual (TM).
(page 1-11, para 3a(2)).
2.
A.
48 km.
The curvature of the earth limits the range of radio
transmission. In the case of multichannel systems, even with
no obstructions, the limit is approximately 48 km.
To
increase the range, you must install relay stations. (page
1-23, para 4).
3.
B.
TD-754.
The configuration models of the AN/TRC-145 vary in the
components they use.
The chart on page 1-31 provides a
matrix of the components required. The 145A model requires
two TD-660s (as do all models) and two TD-754s. (page 1-32,
table 1-1).
4.
A.
S-250.
Modifications of the S-250 house the MSE assemblages and
mount on HMMWVs to provide high mobility and rapid set-
up/tear-down. (page 1-52, para 8).
5.
C.
AN/TRC-190(V) 3.
The (V) 3 model provides the radio linkage for the NCs. LENs
use the (V) 4 model and SENs use the (V) 1 model.

1-56, para 8b(2)).
