Introduction | 5
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.
MODEL 3112
The Model 3112 Double-Ridged Waveguide
Horn Antenna 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.
MODEL 3106B
The Model 3106B Double-Ridged Waveguide
Horn Antenna 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). 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

6 | Introduction
MODEL 3119
The Model 3119 Double-Ridged Waveguide
Horn Antenna is a linearly polarized broadband
antenna covering the frequency range of
400 MHz to 6 GHz.
The Model 3119 is ideally suited for immunity
over 1 GHz and as a reference antenna for
wireless testing. In addition, the 3119 is useful
for antenna pattern measurement as a source
antenna.
MODEL 3115
MODEL 3117
The Model 3115 Double-Ridged Waveguide
Horn Antenna is a linearly polarized broadband
antenna covering the frequency range of
750 MHz to 18 GHz
The Model 3115 is ideally suited for
IEC 61000-4-3 and MIL-STD 461E immunity
tests as well as ANSI C634 and EN 55033
emissions testing. In addition, the 3115 is
useful for antenna pattern measurement as a
source antenna
The Model 3117 Double-Ridged Waveguide
Horn Antenna is a linearly polarized broadband
antenna covering the 1 GHZ to 18 GHz
frequency range.
A single well defined main lobe radiation
pattern over the entire frequency range
provides excellent illumination of the
Equipment Under Test (EUT). The Model 3117
is ideally suited for IEC 6100-4-3 and
MIL-STD 661/462 immunity tests as well as
ANSI C634 and EN 55033 emissions tests.

Mounting Instructions | 17
4.0 Mounting Instructions
Before connecting any components, follow the safety information
in the ETS-Lindgren Product Information Bulletin included with
your shipment.
The ETS-Lindgren Double-Ridged Waveguide Horn Antennas are
precision instruments. Handle with care.
Make sure that no part of the antenna is in contact with the tripod or
tower.
Model 3112 Optional Positioning System
Failure to provide continuous support of the antenna when
attaching or removing the antenna from the positioning system may
result in damage and/or personal injury.
The customer is responsible for providing an adequate and safe
support system for the Model 3112 Double Ridged Waveguide
Horn Antenna when moving and attaching to the optional
positioning system.

18 | Mounting Instructions
The Model 3112 Double Ridged Waveguide Horn antenna includes a series of
outer holes in the rear plate that is compatible with the optional positioning
system. Additionally, the mounting holes can be used to meet customer specific
mounting requirements.

Mounting Instructions | 19
CONNECTING THE OPTIONAL POSITIONING SYSTEM
Once the Model 3112 is securely mounted on the positioner, loosen the nuts and
turn the wheel at the base of the horn support for better field uniformity. This bore
sights the horn 10 degrees.
MODEL 3112 INPUT LOCATIONS
Do not connect power to the positioner until the antenna is
securely mounted and all other connections have been made.
The input panel is located on the base of the Model 3112 positioner.
Plug one end of the fiber optic cable into the FIBER OPTIC INPUT connector.
Plug the opposite end of the fiber optic cable into the ETS-Lindgren Model 2090
Multi-Device Controller or compatible controller.
Plug the cord included first into the POWER SUPPLY outlet. Make connection with
the power source only once all other connections have been made and the
antenna is securely attached to the positioner.

20 | Mounting Instructions
AIR POLARIZATION OPTION
Plug the ends of the twin air hoses into the two AIR OUT connectors located on the
interface box at the base of the custom positioning system.
Plug the opposite ends of the twin hoses into the two 90 degree fittings on the air
cylinder of the custom positioning system.
Plug one end of the single air hose into the AIR IN connector located on the
opposite side of the interface box at the base of the custom positioning system
(shown in previous diagram).
Plug the opposite end of the single air hose into the air supply.
Once the antenna is completely secure and the connections are made, connect the
power supply to the POWER SUPPLY port on the opposite side of the interface
box at the base of the custom positioning system (show in previous diagram).
