AN/GRC-224 Radio Set (Mobile Subscriber Equipment (MSE))

SYSTEM PARAMETERS

SYSTEM DESCRIPTION

The AN/GRC-224 is a line-of-sight radio link for use with the

Frequency: 14.50 15.35 GHz

Power: 0.5 W average

MSE networks that utilizes a 0.6 m parabolic reflector dish

PEP 1 W

antenna mounted on a 15 m telescoping mast. This set is known

as the Down-the-Hill Microwave Communications Radio.

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 and is not subject to radiation protection control.

AN/GRC-226 (V) 1, 2 Radio Set

SYSTEM DESCRIPTION

SYSTEM PARAMETERS

The AN/GRC-226 is a line-of-sight radio link for use

Frequency: 225 - 400 MHz (Band I)

Power: 20 W (Band I)

with the MSE networks that utilizes a 1.1 x 0.9 m

1350 1850 MHz (Band II)

5 W (Band II)

prime-fed reflector dish antenna mounted on a 15 m

telescoping mast.

HAZARD CONTROLS (to reduce or eliminate risk)

SYSTEM HAZARDS

Power Density Levels (PDL) ....

When operating in Band I, 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). When operating in Band II, this system is not

able to produce potentially hazardous PDLs in excess of the safety standard.

Hazard distance from antenna ....

When operating in Band I, exclude personnel to a distance of 0.4 m from the antenna.

Under normal operating conditions, the location of the antenna will prevent personnel

exposure to RFR.

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.
