AN/GRC-233 Communication System

AN/GRC-233 Communication System

SYSTEM DESCRIPTION

SYSTEM PARAMETERS

The AN/GRC-233 consists of the AN/PRC-133 and

Frequency: 2 - 30 MHz (PRC-133)

Power: 125 W PEP (PRC-133)

AN/URC-130 Radio Sets and utilizes a tripod-

225 - 400 MHz (URC-130)

35 W (URC-130)

mounted cross dipole antenna.

SYSTEM HAZARDS

HAZARD CONTROLS (to reduce or eliminate risk)

Power Density Levels (PDL) ....

Both the AN/PRC-133 and AN/URC-130 are able to produce potentially hazardous

PDLs in excess of the safety standard. Under normal operating conditions, due to low

transmitter power and/or low antenna gain personnel exposure to RFR is highly

improbable and this system is not subject to radiation protection controls.

Hazard distance from antenna ....

As a general rule, when operating the AN/PRC-133, exclude personnel to a distance of

30 cm from the antenna. As a general rule, when operating the AN/URC-130, exclude

personnel to a distance of 0.9 m from the antenna.

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

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

AN/GRC-240 VHF/UHF Radio

SYSTEM DESCRIPTION

SYSTEM PARAMETERS

The AN/GRC-240 is a VHF/UHF radio that utilizes a broadband

Frequency: 116 - 400 MHz

Power: 30 W

vertical monopole antenna mounted on a bracket 1.8 m above ground on

the left rear corner of the High Mobility Multipurpose Wheeled Vehicle

(HMMWV).

HAZARD CONTROLS (to reduce or eliminate risk)

SYSTEM HAZARDS

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.

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

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