ETS-Lindgren 3125 Precision Dipole Antenna - Manual (Page 7)

1.0 Introduction
The ETS-Lindgren Model 3125
Series Fixed Length Dipole is a
family of antennas that are tuned to
operate between 440 MHz and
3010 MHz.
The Model 3125 Series is designed
for AAMI/FDA test requirements,
which substitute dipole antennas for
cellular telephones as an emissions
source when testing the
susceptibility of items such as
pacemakers, hearing aids, and
defibrillators.
The most common frequencies in the Model 3125 Series are included
in this manual. Additional frequencies are available; contact
ETS-Lindgren for more information.
The Model 3125 Series antennas are tuned, half-wave length resonant dipoles
with a series-parallel coaxial stub balun. Each antenna has fixed-length dipole
elements mounted in a Teflon® support block. The coaxial balun is terminated
into an SMA receptacle. Individual calibration data is included with each antenna.
An optional bracket is available to mount the Model 3125 Series antenna to an
ETS-Lindgren tripod or other positioning system. See Mounting Instructions on
page 15 for more information.
Use only non-metallic material for any label to be applied to the
Model 3125 Series. Testing has shown that applying a foil-backed
label adversely affects the tuned characteristics of the antenna.
