|  SYSTEM PARAMETERS
SYSTEM DESCRIPTION
The AN/GSC-39 is a satellite communications ground terminal
Frequency: 7.9 8.4 GHz
Power: 10 kW PEP
that utilizes a 11.6 m diameter parabolic dish antenna.
70 W average
HAZARD CONTROLS (to reduce or eliminate risk)
SYSTEM HAZARDS
Power Density Levels (PDL) ....
At high power outputs, 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).
Hazard distance from antenna ....
At maximum power output, do not direct the antenna within 1578 m of potentially
occupied areas or elevated structures. Maintain a positive elevation angle to prevent
RFR exposure to personnel.
Open/cracked waveguides ........
All open waveguides and feed horn outputs produce hazardous PDLs at close range.
Exclude personnel to a distance of 4.2 m from any open waveguide.
Consult the equipment Technical Manual for other operator and/or maintenance hazards.
Other.................................
Test all interlocks periodically. Specify the use of a dummy load for maintenance
procedures requiring the transmitter to be on.

AN/GSC-40 Satellite Communications System
SYSTEM DESCRIPTION
SYSTEM PARAMETERS
The AN/GSC-40 is a satellite communications system that
Frequency: 225 400 MHz
Power: 500 W PEP
utilizes a quad-array or dipole-fed reflector dish antenna mounted
100 W average
on a 2 m mast.
HAZARD CONTROLS (to reduce or eliminate risk)
SYSTEM HAZARDS
Power Density Levels (PDL) ....
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).
Hazard distance from antenna ....
Exclude personnel to a distance of 7.0 m from the antenna feed plane. In the Emergency
Action Mode (EAM), exclude personnel to a distance of 10 m from the antenna.
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.
