AN/APN-158\AN/APN-158A Radar Set  (part of MULT ACFT)
SYSTEM DESCRIPTION
SYSTEM PARAMETERS
The AN/APN-158 is an airborne weather radar that utilizes either the AS-1520 or
Frequency: 9375 MHz
AS-1624 parabolic dish antenna.
Power: 12 W average; PEP 15 kW
26.4 W average; PEP 20 kW (A)
SYSTEM HAZARDS
HAZARD CONTROLS (to reduce or eliminate risk)
Power Density Levels (PDL) .....
In the normal operating mode, this system is able to produce potentially hazardous PDLs
in excess of 5 x the safety standard and requires a formal RFR safety program to ensure
its safe use. While scanning, this system is not able to produce PDLs in excess of the
standard. Establish a Nonionizing Radiation Protection Program (IAW guidelines
provided in this TB) .
Hazard distance from antenna ....
When operating the AN/APN-158, exclude personnel to a distance of 2.4 m from the
AS-1520 antenna and 3.6 m from the AS-1624 antenna. When operating the AN/APN-
158(A), exclude personnel to a distance of 3 m from the AS-1520 antenna and 4.7 m
from the AS-1624 antenna.
Open/cracked waveguides .......
Do not permit operation of this system with any cracked, broken, or open waveguide.
Check waveguide portion of this system periodically for breaks or cracks, and replace
any suspect waveguide.
Other.................................
Consult the equipment Technical Manual for other operator and/or maintenance hazards.

AN/APN-171\AN/APN-171A Altimeter Set
SYSTEM PARAMETERS
SYSTEM DESCRIPTION
The AN/APN-171 is an airborne, low altitude, terrain tracking and
Frequency: 4.3 GHz
altitude sensing radar system that utilizes an antenna with a 13 dB gain.
Power:  Low: 35 mW average; PEP 100 W
This system operates in two power modes.
High: 390 mW average; PEP 300 W
SYSTEM HAZARDS
HAZARD CONTROLS (to reduce or eliminate risk)
Power Density Levels (PDL) ....
In the low power mode, this system is not able to produce potentially hazardous PDLs in
excess of the safety standard. In the high power mode, this system is capable of
producing 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 ....
When operating in the high power mode, exclude personnel to a distance of 10 cm from
the antenna.
Other.................................
Consult the equipment Technical Manual for other operator and/or maintenance hazards.
