AN/FRC-173 (V) 1 12 Radio Set

AN/FRC-173 (V) 1 12 Radio Set

SYSTEM DESCRIPTION

SYSTEM PARAMETERS

The AN/FRC-173 is a general purpose radio set which utilizes

Frequency: 7.06 8.07 GHz

Power: 3.5 W average

4.33 5.07 GHz

several various aperture type antennas that are normally

mounted on towers.

SYSTEM HAZARDS

HAZARD CONTROLS (to reduce or eliminate risk)

Power Density Levels (PDL) ....

This system, under certain configurations, is able to produce potentially hazardous PDLs

in excess of the safety standard. Direct the antenna main beam away from occupied

structures. Establish a Nonionizing Radiation Protection Program (IAW guidelines

provided in this TB) .

Open/cracked waveguides .......

All open waveguides and loose or open flanges produce potentially hazardous PDLs

within close proximity of the break. Exclude personnel from these areas and do not

permit operation of this system with any cracked, broken or open waveguide.

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

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

AN/FRC-181 Satellite Communications Terminal (part of Ground Command Post

Terminal)

SYSTEM PARAMETERS

SYSTEM DESCRIPTION

The MILSTAR AN/FRC-181 is a fixed millimeter wave satellite communications

terminal that utilizes a 2.44 m diameter parabolic reflector antenna.

SYSTEM HAZARDS

HAZARD CONTROLS (to reduce or eliminate risk)

Power Density Levels (PDL) ....

This system is not able to produce potentially hazardous PDLs in excess of the safety

standard.

Open/cracked waveguides.......

The area between the feed horn and the reflector produce potentially high PDLs. All

open waveguides produce potentially hazardous PDLs within 2.5 cm. Exclude

personnel from these areas and check waveguide portion of this system periodically for

breaks or cracks, and replace any suspect waveguide.

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

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