1.0 Introduction
The ETS-Lindgren family of Double-Ridged Waveguide Horn Antennas
consists of linearly polarized broadband antennas ranging in frequency from
100 MHz to 40 GHz. These antennas were designed and built specifically from
EMI measurements and specifications compliance testing. However, they can
also be used for antenna gain, pattern measurement, surveillance, automotive,
and military EMC immunity applications.

3112
The Model 3112 Double-Ridged
Waveguide Horn is a linearly polarized
antenna covering the frequency range
of 100 MHz to 1 GHz.
The Model 3112 is especially effective
for generating high electromagnetic
fields with relatively low power input.
The antenna is also useful for receiving
low-level signals where high gain
characteristics are needed.

3106B
The Model 3106B Double-Ridged
Waveguide Horn is a linearly polarized
broadband antenna covering a
frequency range of 200 MHz to
2.5 GHz. It is precision-machined from
aluminum, making it lightweight and
durable. Two brackets are attached to
the sides of the antenna so it can be
polarized either horizontal or vertically.
The Model 3106B has high gain and excellent VSWR characteristics over the
entire frequency range (see Appendix B on page 51 for data charts). It is
especially effective for generating high electromagnetic field with relatively low
power input. The antenna is also useful for receiving low level signals where high
gain characteristics are needed.
