c. Antenna Group, Direction Finder Set AN/TRQ 30(V).

Refer to figure 1-5. Antenna Group, Direction Finder Set

AN/TRQ-30(V) consists of three different groups: HF Antenna

Group AN/TRQ-30(VI), VHF Antenna Group AN/TRQ-30(V2),

and HF/VHF Antenna Group AN/TRQ-30(V4). The antenna

groups include interchangeable loop antennas and associated

support equipment which are used in conjunction with the various

configurations of the radio receiver set. Four loop antennas

cover the 0.5 to 157 MHz frequency range and enable the

operator to locate the position of transmitters, operating within

these ranges, through detection and triangulation methods. The

following paragraphs briefly describe the major components of

the antenna groups.

(1) Antenna

AS-1523/TRQ-30(V).

Antenna

AS1523/TRQ-30(V) is an HF loop antenna for direction finding in

the 0.5 to 20.5 MHz range. The antenna contains circuitry for

band switching and tuning. All operating controls and switches

are located on the base of the antenna.

(2) Antenna

AS-1526/TRQ-30(V).

Antenna

AS1526/TRQ-30(V) is an 11-inch diameter VHF loop antenna for

direction finding in the 19 to 50 MHz range. The antenna

contains frequency matching circuitry operated by a control

mounted on the base of the antenna.
