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.
