AN/TRC-190 (V) 1 Line-of-Sight (LOS) Multichannel Radio Terminal

AN/TRC-190 (V) 1 Line-of-Sight (LOS) Multichannel Radio Terminal

SYSTEM PARAMETERS

SYSTEM DESCRIPTION

The AN/TRC-190 line-of-sight radio link is a mobile

Frequency: 225 - 400 MHz (Band I)

Power: 20 W (Band I)

subscriber equipment (MSE) assemblage that utilizes the

610 960 MHz (Band II)

10W (Band II)

AN/GRC-226 Radio Set. The MSE utilizes a whip

1350 1850 MHz (Band III)

5 W (Band III)

antenna.

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 Bands II & III, 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.

AN/TRC-194 (V) 2 MILSTAR Ground Command Post Terminal

SYSTEM DESCRIPTION

SYSTEM PARAMETERS

The MILSTAR AN/TRC-194 is a transportable millimeter wave satellite

Frequency: 225 400 MHz (UHF)

communications terminal. The EHF portion of the system utilizes a 2.44 m diameter

parabolic reflector antenna. The UHF portion of the system utilizes a transmitter and

Power: 100 W (UHF)

a phased array antenna of five dipoles mounted on a tower.

SYSTEM HAZARDS

HAZARD CONTROLS (to reduce or eliminate risk)

Power Density Levels (PDL) ....

The EHF portion of the system is able to produce potentially hazardous PDLs in excess

of the safety standard between the antenna feed and the reflector. The UHF portion of

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

standard in the antenna main beam.

Open/cracked waveguides.......

For the EHF portion, the area between the antenna feed 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.

RF shock/burn......................

Observe standard RF shock precautions. Do not touch either antenna when energized.

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

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