1.0 Introduction
The ETS-Lindgren Model 3117 Double-Ridged Waveguide Horn Antenna is a
linearly polarized broadband antenna covering the 1 to 18 GHz frequency range.
The Model 3117 antenna was designed and built specifically for EMI
measurements and specifications compliance testing. However, it can also be
used for antenna gain, pattern measurement, surveillance, and other
applications.
A single well-defined main lobe radiation pattern over the entire frequency range
provides excellent illumination of the EUT. The Model 3117 antenna is ideally
suited for IEC61000-4-3 and MIL-STD 461/462 immunity tests as well as ANSI
C634 and EN 55033 emissions tests.
The Model 3117 antenna is precision machined from aluminum. A 50-ohm
precision high frequency type N connector is mounted on the base block of the
antenna. A mounting bracket is provided for tower and tripod mounting in
horizontal and vertical polarization positions.
1.1 Standard Configuration
• Antenna assembly
• Mounting bracket configured to accept ETS-Lindgren or other tripod mounts
with ¼ inch x 20 threads. In addition to the mounting bracket, a stinger mount
is provided for on-axis rotation during polarization.
• Individually calibrated at 1 meter per SAE ARP 958 at the ETS-Lindgren
A2LA accredited calibration lab. A 3-meter calibration per ANSI C63.5 is
available at additional cost. Actual antenna factors and a signed Certificate of
Calibration Conformance are included.

evidence of damage. Record any damage on the delivery receipt before signing
it. In case of concealed damage or loss, retain the packing materials for
inspection by the carrier.
Step 2. Remove the product from its shipping container(s). Save the container(s)
and any protective packing materials for future use.
Step 3. Check all materials against the packing list to verify that the equipment
you received matches what was ordered. If you find any discrepancies, note
them and call ETS-Lindgren Customer Service for further instructions.
Ensure that you are satisfied with the contents and condition of your order prior
to placing the product into service.

3.0 Maintenance
To ensure reliable and repeatable long-term performance, annual recalibration of
your antenna by ETS-Lindgren experienced technicians is recommended. Our
staff can recalibrate almost any type or brand of antenna. Please call to receive a
Service Order Number prior to sending an antenna for calibration.

4.0 Mounting Instructions
The Model 3117 Double-Ridged Waveguide Horn Antenna includes these
components:
• Double-Ridged Waveguide Horn
• Mounting bracket with two ¼ inch x 20 threaded connectors
• Stinger mount for centerline rotation

The Model 3117 antenna can be mounted in three different configurations:
• With the mounting bracket
• With the stinger mount and special boom (for centerline polarization)
• With a clamp block
4.1 Using the Mounting Bracket
The U-shaped mounting bracket features a ¼ inch x 20 threaded connector at
one end of the bracket, and another ¼ inch x 20 threaded connector at the other
end. This design allows mounting from either end of the bracket. Because the
threaded connectors are different distances from the center of the bracket,
flipping the bracket results in one end longer than the other, constructed to
support a variety of mounting scenarios.
Mounting Instructions | 13

4.1.1 Mount the Bracket onto a Tripod
The mounting bracket can be attached to an ETS-Lindgren or other tripod mount.
Using either of the threaded connectors on the mounting bracket, attach the
bracket to the ¼ inch x 20 threaded connection on the tripod.
4.1.2 Mount the Bracket onto an ETS-Lindgren Tower Boom
Insert a ¼ inch x 20 threaded knob through the tower boom and attach it to either
of the threaded connectors on the mounting bracket.
4.1.3 Attach the Antenna to the Mounting Bracket
1. Insert the threaded mounting stud on the back of the Model 3117 antenna
through the center hole on the mounting bracket.
2. Align the Model 3117 antenna for horizontal or vertical polarization by
inserting the two polarization orientation studs on the back of the antenna
into the holes on the mounting bracket.
3. Secure the Model 3117 antenna into place by carefully threading the stinger
onto the threaded mounting stud on the back of the antenna. Do not cross-
thread, or permanent damage to the antenna could occur.
4.2 Using the Stinger Mount
The stinger can be used to mount the Model 3117 antenna into either a clamp
block mount that attaches to a standard boom or the new stinger mount
compatible boom. The stinger mount compatible boom allows the antenna to be
polarized along the centerline without the need for an offset boom.
Please contact the ETS-Lindgren Sales Department for information about
the Clamp Block (part number 102108) or Stinger Mount Boom.
4.2.1 Mount the Antenna into the Stinger Mount Boom
With the stinger securely attached to the Model 3117 antenna, slide the stinger
into the receptacle at the end of the boom and secure it into place using the knob
attached to the boom.
4.2.2 Mount the Antenna into a Clamp Block
1. Secure the clamp block to the tripod or tower boom.
2. Open the clamp by loosening the wing nut until the swing latch opens.
14 | Mounting Instructions

3. Open the clamp and place the stinger in the circular portion of the clamp. The
stinger should be inserted into the clamp so that the antenna is close to the
clamp.
4. While holding the stinger, close the top of the clamp over the antenna and
secure it into place with the swing latch and wing nut.
4.3 Attach a Cable to the Type N Connector
After mounting the Model 3117 antenna onto the tripod or tower for testing,
connect an N-type coaxial cable from the type N connecter on the antenna to a
signal generator or amplifier.

The radiation pattern of the Model 3117 antenna makes it ideal for any set up
where uniform illumination of a target is necessary. With beamwidths around
35 degrees for both planes, this single antenna can be used in place of a set of
eight standard gain horns.
Each Model 3117 antenna is individually calibrated at 1 meter per SAE ARP 958.
Factors for the antenna, with apparent gain at 1 meter from the end of the
antenna, have been determined and are included with the antenna along with a
signed Certificate of Calibration Conformance.
This factor should be used in specification compliance testing to convert receiver
reading (dBuV) to field intensity units (dBuV/M). The conversion is accomplished
by adding the antenna factor in dB to the receiver reading in dB above
1 microvolt.
