AN/GRC-106A Radio Set (used in AN/VSC-2, AN/VSC-3)

AN/GRC-103 (V) 1, 2, 3, 4 Radio Set (used in AN/TRC-145, AN/TRC-173, AN/GRC-174,

AN/TRC-180)

SYSTEM DESCRIPTION

SYSTEM PARAMETERS

The AN/GRC-103 is a line-of-sight UHF-FM radio set that

Frequency: 220 - 405 MHz

Power: 25 W average

utilizes several aperture-type antennas, i.e., corner reflector

395 705 MHz

30 W PEP

(Bands I, II, III) and 0.9 m parabolic reflector (Bands IV)

695 1000 MHz

antenna. For operational effectiveness, the antennas are

1350 1850 MHz

normally mounted at least 3 m above ground.

SYSTEM HAZARDS

AN/GRC-106A Radio Set (used in AN/VSC-2, AN/VSC-3)

SYSTEM PARAMETERS

SYSTEM DESCRIPTION

The AN/GRC-106 is a two way high frequency voice

Frequency: 2 30 MHz

Power: 200 W average

communications radio system that utilizes an omnidirectional

400 W PEP

whip-type antenna. For operational effectiveness, the antenna

is normally mounted on a vehicle or radio-shelter roof.

HAZARD CONTROLS (to reduce or eliminate risk)

SYSTEM HAZARDS

Power Density Levels (PDL) ....

This system is able to produce potentially hazardous PDLs in excess of the safety

standard. Establish a Nonionizing Radiation Protection Program (IAW guidelines

provided in this TB) .

Hazard distance from antenna ....

Exclude personnel to a distance of 1.5 m from the antenna.

RF shock/burn .....................

Observe standard RF shock precautions. Do not touch the antenna when energized.

Other.................................

Consult the equipment Technical Manual for other operator and/or maintenance hazards.

Do not operate the system in a free space radiating mode inside of buildings.
