Introduction
1.0 Introduction
The
ETS-Lindgren Model 3158 High Field Biconical Antenna
is specifically
designed for Immunity testing.
This linearly-polarized
transmit antenna is
optimized to generate
high levels of
electromagnetic fields in
the range of 20 MHz to
120 MHz.
Model 3158 shown with pedestal
The ability of the Model 3158 to handle high power levels over a broadband
makes it excellent for use in Radiated Susceptibility testing.
The biconical elements are made from welded aluminum tubing. The 4-to-1 ratio
balun network is fabricated from G10 fiberglass and specially machined brass
and aluminum support and contact parts. The bifilar inductors of the balun are
wound in precision-machined cuts to provide high barrier insulation between
windings while simultaneously giving good coupling between bifilar windings.
During manufacturing each Model 3158 is individually calibrated using the
three antenna method of calibration. The results of the calibration are tabulated
and included with the antenna.
