composed of the transceiver portion of the AN/PRC-66A and
the 943B-1 power amplifier. The AN/PRC-66A is a portable
transceiver which provides AM communication on any one of
3,500 channels in the 225.0 to 399.95 MHz ultra-high frequency
range. The average power output is 2 watts which is used to
drive the 943B-1 UHF amplifier. The 943B-1 is a broadband
power amplifier capable of providing a 10-watt rf power out-
put in the 225 to 400 MHz frequency range. The 943B-1
requires a minimum input of 0.5 watts to produce the rated
output. Coaxial cable attenuation at the high end of the
frequency range limits the distance the power amplifier can
be remoted from the transceiver to a maximum of 150 feet.
(7) Antenna System -
(i) HF Circuit - The antenna system for the hf link will
consist of the 490B-4 antenna coupler and the AS-2047/TRC
whip antenna. The 490B-4 consists of the 490T-2 automatic
antenna coupler, load coil, switching relay, and cooling
blower all contained in an environmentally sealed housing.
The 490T-2 is an automatically tuned hf antenna coupler

Approved For Release 2006/09/25 : CIA-RDP721300464R000600010004-5
designed to tune wire and whip antennas in the frequency
range of 2 to 30 MHz. The coupler has an input power rating
of 500 watts average. The 490B-4 has a T/R switch, but this
will not be used in the normal operating configuration. A
coaxial relay mounted on the 499R-13 shelf in the equipment
cabinet will serve as the system T/R switch. A "tee" connec-
tion off of the relay will provide a secondary receive input.
The AS-2047/TRC is a 32 foot fiber whip antenna which will
mount directly on to the 490B-4 coupler. The AS-2047/TRC is
assembled from 4 foot sections.
The coaxial feed between the 718U-4 transceiver and the 490B-4
coupler will consist of three, 100 foot sections of Andrew
FSJ4 Superflex coaxial cable.
(ii) UHF Circuit - The uhf antenna to be used will be the
837D-1 UHF blade antenna. The 837D-1 is a lightweight, broad-
band antenna designed for operation within the 225 to 400 MHz
frequency range. The antenna is a vertically polarized mono-
pole with an input impedance of 50 ohms.
The 837D-1 will be attached to a combination ground plane/sun-
shade with the 943B-1 power amplifier mounted directly under-
neath.

control of the hf radio and circuit patching capability.
The 714E-6 control unit is mounted on the panel to provide
frequency and mode control to the hf transceiver. Dual
speakers with independent volume controls are provided on
the panel to allow simultaneous monitoring of both hf
receivers. Dual 1000 Hz CW tones are switch selectable-from
the panel to provide a patchable input to the radio circuit.
The audio circuits from the GFE fsk modems are brought to the
patch panel. One circuit is normalled through to the hf
equipment, the backup circuit is available on a patched basis.

Antenna System
(i) HF Circuit
- The antenna system for the 718U-4 hf trans-
ceiver will utilize the identical system as described in
section 3.1.1.1.6a(7). The only addition is that the coaxial
feed line will consist of four, 100 foot sections of Andrew
FSJ4 Superflex coaxial cable.
The antenna to be used with the GFE hf receiver is the
AS2046/TRC whip antenna. The AS2046/TRC is similar to the
AS2047/TRC, the only difference ?is in the base plate and rf
connector assembly.
