AN/TSC-152 Lightweight Multiband Satellite Terminal (LMST) Transit Case

SYSTEM DESCRIPTION

SYSTEM PARAMETERS

The AN/TSC-152 is a transportable tactical satellite communications (SATCOM)

Frequency: 6135 MHz (C-Band)

terminal which can transmit and receive satellite data in three frequency bands.

8150 MHz (X-Band)

The system electronics are enclosed in seven separate carrying cases. Each LMST

14.25 GHz (Ku-Band)

Transit Case antenna is equipped with three interchangeable feed horn assemblies

which are fed by three separate waveguides. The system utilizes a continuous wave

Power: 290 W (C-Band)

antenna (transit case) and an external field-mounted continuous wave antenna.

356 W (X -Band)

267 W (Ku-Band)

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 the safety

standard in all three transmit frequency bands. Establish a Nonionizing Radiation

Protection Program (IAW guidelines provided in this TB) .

Hazard distance from antenna ....

When operating in the C-Band, exclude personnel to a distance of 54 m (whole-body)

and 38 m (partial-body) from the antenna. When operating in the X-Band, exclude

personnel to a distance of 85 m (whole-body) and 60 m (partial-body) from the antenna.

When operating in the Ku-Band, exclude personnel to a distance of 115 m (whole-body)

and 82 m (partial-body) from the antenna. Construct an RFR control area of 35 m long

by 10 m wide when the LMST Transit Case System is installed in a remote location.

Maintain surveillance of the area.

Open/cracked waveguides.......

At maximum power the antenna feed horn, parabolic reflector, and all open waveguides

produce potentially hazardous PDLs. Periodically inspect waveguides for cracks or

leaks and replace suspect waveguides. Support all flexible waveguide runs with a cable

to prevent stress at the waveguide flange. Exclude personnel to a distance of 1-2 m from

any open or broken waveguide.

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

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

Specify the use of dummy loads for maintenance operations.
