|  AN/SPN-11X,Y, Z Radar Set
SYSTEM PARAMETERS
SYSTEM DESCRIPTION
The AN/SPN-11 is a shipboard navigation system that utilizes
Frequency: 9.32 9.43 GHz
Power: 12 W average
a horn-fed parabolic section reflector antenna.
30 kW PEP
HAZARD CONTROLS (to reduce or eliminate risk)
SYSTEM HAZARDS
Power Density Levels (PDL) ....
In the scanning mode, this system is not able to produce potentially hazardous PDLs in
excess of the safety standard. Do not operate this system in the radiate mode while the
vessel is in port.
Hazard distance from antenna ....
In the nonscanning mode, the area between the horn and reflector is extremely
hazardous. Exclude personnel from this area.
Open/cracked waveguides .......
Periodically inspect waveguides for cracks or leaks and replace suspect waveguides.
Other.................................
Consult the equipment Technical Manual for other operator and/or maintenance hazards.

AN/SPN-41 Aircraft Approach Guidance
SYSTEM DESCRIPTION
SYSTEM PARAMETERS
The AN/SPN-41 transmits glideslope and centerline
Frequency: 15.412 15.688 GHz
Power: 7.5 W average
deviation information to approaching aircraft. This system
2 kW PEP
utilizes two antennas; an azimuth pillbox-parabolic reflector
and elevation pillbox parabolic reflector antenna.
HAZARD CONTROLS (to reduce or eliminate risk)
SYSTEM HAZARDS
Power Density Levels (PDL) ....
In the scanning mode, this system is not able to produce potentially hazardous PDLs in
excess of the safety standard. In the nonscanning mode, 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 ....
In the nonscanning mode, exclude personnel to a distance of 2.8 m from the azimuth
antenna and a distance of 1.7 m from the elevation antenna.
Open/cracked waveguides .......
Periodically inspect waveguides for cracks or leaks and replace suspect waveguides.
Other.................................
Consult the equipment Technical Manual for other operator and/or maintenance hazards.
