Introduction | 9
1.0 Introduction
The ETS-Lindgren End Fed Mini-Bicons includes these two groups of
broadband omni-directional antennas:
Model 3181 / Model 3184
The Model 3181/3184 is designed for
surveillance, spectrum monitoring, and
shielding tests.
The frequency range for the Model 3181 is
500 MHz to 9 GHz and the frequency range
for the Model 3184 is 1 GHz to 18 GHz.
The Model 3181 performs best up to
9 GHz, but is usable to 18 GHz if
amplification is used. The Model 3184
performs better than the Model 3181 in the
9 GHz to 18 GHz range. Data to 18 GHz is
provided for both antennas.
The radome provides weather protection for
outdoor testing, and a weatherizing kit is
included to protect the antenna connection.
Model 3183
The Model 3183 is designed for
CISPR 16-1-4 chamber validation testing
above 1 GHz. The frequency range for the
Model 3183 is 1 GHz to 18 GHz.
The Model 3183 is not weather protected,
and is not recommended for outdoor
testing.
Never attempt to remove the stem from the Model 3183.

10 | Introduction
The radiation pattern is omni-directional in the H-plane, allowing the antenna to
receive signals from every direction around the axis. The range covers most
wireless bands worldwide, and is designed for the lowest possible VSWR across
the range of operation. The antenna exhibits better than 2:1 VSWR for most of
the range, and never exceeds 5:1 above 1 GHz.
The small sizes of the antennas enable them to be used for amplifier harmonic
measurements when performing tests per IEC 61000-4-3.
Each antenna is calibrated during manufacturing. The results of the calibration
are tabulated as gain and antenna factor vs. frequency for use in Specification
Compliance Testing. Typical data is provided starting on page 29.
The Model 3181/3183/3184 includes a stinger mount and ships with an antenna
mount assembly for a variety of mounting configurations. For information on the
4-TR, see the next section, Tripod Options; for mounting information, see
Mounting Instructions on page 17.
Tripod Options
ETS-Lindgren offers the 4-TR
non-metallic, non-reflective tripod for use
at both indoor and outdoor EMC test
sites.
•Constructed of linen phenolic and
delrin, designed with an adjustable
center post for precise height
adjustments.
•Maximum height is 2.0 m (80.0 in),
and minimum height is 94 cm
(37.0 in).
•Can support up to an 11.8 kg (26.0 lb)
load.

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 Model 3181/3183/3184 antennas are
precision measurement devices. Handle your
antenna with care.

18 | Mounting Instructions
Using the Antenna Mount Assembly on a 4-TR
The antenna mount assembly ships with this
larger knob in place of the thumbscrew shown
in the following photos. The larger knob
provides the same functionality but provides
increased usability.
Each Model 3181/3183/3184 End Fed Mini-Bicon Antenna ships with an antenna
mount assembly for a variety of mounting configurations. To use the antenna
mount assembly with an ETS-Lindgren 4-TR Tripod, select the antenna mounting
orientation, attach the antenna mount assembly to the 4-TR, and then attach the
antenna to the antenna mount assembly. Each step is detailed in the following
sections.

Mounting Instructions | 19
STEP 1: ATTACH ANTENNA MOUNT ASSEMBLY TO 4-TR
You may use the antenna mount assembly to mount the Model 3181/3183/3184
in vertical or horizontal orientation.
•Vertical orientation:
Attach the extension to
the threaded insert on
the bottom of the
mount and rotate to
tighten into place.
Attach the extension
to the 4-TR using the
threaded insert on the
bottom of the
extension. Turn the
extension to secure
the antenna mount
assembly to the 4-TR.
•Horizontal
orientation: You may
attach the antenna
mount assembly
directly to the 4-TR, or
you may use the
extension to attach it
to the 4-TR.

20 | Mounting Instructions
To direct mount, attach the mount to the 4-TR using the threaded insert on the
side of the mount. Rotate to tighten into place.
To use the extension, attach the extension to the mount using the threaded
insert on the side of the mount, and then turn the extension to tighten. Attach the
extension to the 4-TR using the threaded insert on the bottom of the extension.
Rotate to tighten into place.
