AN/TRC-170 (V) 1, 2, 3 Radio Terminal Set

SYSTEM DESCRIPTION

SYSTEM PARAMETERS

The AN/TRC-170 is a transportable radio terminal set used for

Frequency: 4.4 5.0 GHz

Power: 2.0 kW PEP

troposcatter communications. This set utilizes two parabolic

reflector (2.9 m or 1.8 m diameter) antennas.

SYSTEM HAZARDS

HAZARD CONTROLS (to reduce or eliminate risk)

Power Density Levels (PDL) ....

This system is able to produce potentially hazardous PDLs in excess of 5x the safety

standard and requires a formal RFR program to ensure its safe use. Establish a

Nonionizing Radiation Protection Program (IAW guidelines provided in this TB) .

Hazard distance from antenna ....

When using the 2.9 m antenna, exclude personnel to a distance of 140 m from the

antenna (controlled area) or 255 m for uncontrolled areas. When using the 1.8 m

antenna, exclude personnel to a distance of 92 m from the antenna (controlled area) or

168 m for uncontrolled areas.

Open/cracked waveguides.......

The area between the feed and the reflector and any open waveguide produce potentially

hazardous PDLs. Periodically inspect waveguides for cracks or leaks and replace

suspect waveguides. Exclude personnel to within 2 m of any open waveguides.

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

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