A.H. Systems Model SAS-551 Passive Monopole Antenna
OPERATING INSTRUCTIONS
ASSEMBLY INSTRUCTIONS
To prepare the antenna for operation, attach the telescoping rod antenna
element to the top of the ground plane box.
Connect the rod antenna by pushing straight down on the female
connector on top of the amplifier. Do not apply excessive sideways force,
as this can cause the antenna center-pin to break.
SETUP INSTRUCTIONS
The ground plane can be mounted to any tripod with a 1/4-20 attaching stud.
Extend the rod antenna to 41" (104 cm) above the ground plane. Connect the
output BNC connector on the side of the antenna to the output of a 50
generator or amplifier. Establish a ground connection to the ground plane if
required by the test specification.
GENERAL USE INSTRUCTIONS
The SAS-551 Monopole antenna is a passive antenna designed to transmit
high electric fields
This antenna may also be used as a passive receive antenna for testing in
areas with high fields.
Each antenna is individually calibrated per ANSI C63.5 (ECSM) and comes with
a calibration certificate references the NIST traceable test equipment.
The calibration tables shown provide a listing of the frequency of operation and
its antenna factor in dB/m. The field strength is the receiver voltage in dBV
plus the antenna factor (refer to the antenna factor calibration) plus any cable
loss. When making a measurement, mount the antenna on an appropriate mast
or tripod.
