The ETS-Lindgren Model 7-TR Tripod
Positioner is designed for EMC testing,
providing increased stability for physically large,
ultra-broadband antennas, such as
ETS-Lindgren BiConiLog™ antennas. The 7-TR
boom height can be adjusted up and down from
one to two meters (3.3 to 6.6 ft), and can support
antennas up to 13.6 kg (30 lb). The fiberglass
and high-strength plastic construction makes it
non-conductive and non-magnetic.
7-TR/POL-M shown
without boom
Specify the type of boom required when ordering a 7-TR with manual
or pneumatic polarization; a boom is not included. For a list of
available booms, see Boom Options on page 11.
1.0 Introduction
Page 10

Introduction
www.ets-lindgren.com
The boom is attached to the carrier and is locked into position with a
hand knob clamp. Standard mount knobs are included with the boom
to attach antennas securely to the boom.
Three horizontal legs extend from the base to support the mast and
maximize stability. Each leg has a caster with height adjustment for
leveling the mast on uneven surfaces. For convenient storage, the legs
can be folded upward and the top section of the mast removed.

Boom Type
Function
Straight (109042)
For general antenna mounting on a 7-TR.
Offset (108983)
For general antenna mounting on a 7-TR
with pneumatic or manual polarization. Can
also be used to mount stinger-type
antennas.
Stinger Only (118947)
For stinger mount antennas only.
Centerline Rotation (108507)
For Model 3106 Series antennas only; when
changing polarization, maintains centerline
rotation.
For mounting information, see Mounting a
Model 3106 Series Antenna on page 29.
Boom Options
A variety of booms for the 7-TR are available, depending on your antenna
model(s) and polarization requirements. For additional information see
Replacement and Optional Parts on page 18.
Polarization Options
The 7-TR is available with no polarization, with pneumatic polarization, or with
manual polarization; the following sections describe each option. Additionally, a
kit is available to upgrade an existing 7-TR from no polarization or manual
polarization to pneumatic polarization. See Pneumatic Polarization Upgrade Kit
on page 35 for more information.
Page 12

The 7-TR with no
polarization option
includes a standard
boom assembly
(109042) for general
antenna mounting.
For information on
assembling a 7-TR,
see page 25. For
information on using
the 7-TR, see
page 43.
7-TR WITH NO POLARIZATION

Introduction

Specify the type of boom required when ordering a 7-TR with manual
or pneumatic polarization; a boom is not included. For a list of
available booms, see Boom Options on page 11.
The 7-TR with pneumatic
polarization enables
remote rotation of an
antenna between
horizontal and vertical
positions while maintaining
a constant rotational axis
for the centerline of the
antenna. A coax cable
guide at one end minimizes
stress on cables during
use.
7-TR WITH PNEUMATIC POLARIZATION
Page 14
14
Introduction
www.ets-lindgren.com
The 1/4-in air hoses are UV stabilized with a 1/8-in National Pipe
Thread (NPT) fitting. The customer may supply a metric fitting for a
4-mm tube.
The pneumatic polarization option consists of the following components:
Air cylinder—Attaches to the carrier.
The air cylinder is made of non-conductive material, and is connected
by 6.3-mm (1/4-in) tubing to the Air Polarization Interface mounted to
the base of the 7-TR. The air cylinder will polarize antennas up to
13.6 kg (30 lb).
Twin air hose—Connects to Air Output.
Air hose—Connects to Air Input.
Air Polarization Interface—Mounts to the rear of the 7-TR mast.
The Air Polarization Interface requires 120 VAC (230 VAC is optional),
and approximately a 0.28 cubic meters/minute (1 CFM) air supply at
6 bars (90 PSI).
Pneumatic Interface—Mounts to the rear of the 7-TR mast, above the
Air Polarization Interface.
Fiber optic cable—Using a controller such as the Model 2090
Multi-Device Controller (or next generation ETS-Lindgren controller, if
applicable), enables horizontal and vertical boom rotation.
An air supply of 0.28 cubic meters per minute (1 CFM) at 6 bars (90 PSI) is
required for the pneumatic polarization option. It is important to have clean, dry
air; the use of a 40-micron filter in close proximity to the tripod installation is
recommended (not included).
For information on assembling a 7-TR, see page 25. For information on using the
7-TR, see page 43. For information on using the polarization option, see
page 46.

4. Install the boom:
Orient the boom so the mounting holes are to the front of the
7-TR. If the boom has a cable guide (not shown), orient the
cable guide to the rear of the 7-TR.
If the boom has a cable guide, remove the cable guide from the
end of the boom.
Insert the end of the boom through the front and rear
carrier collars, leaving five inches of boom on the hand knob
clamp side of the carrier.
Secure the boom with the 1/4-20 set screws located in the

Before connecting any components or
operating the Model 7-TR, follow the safety
information in the ETS-Lindgren
Product Information Bulletin included with
your shipment.
You will need assistance from two team members
to mount a Model 3106 Series antenna to the 7-TR.
You must install the 108507 boom onto the 7-TR before performing
these steps. For clarity, the following illustrations do not show the
7-TR.
ETS-Lindgren may substitute a similar part with the same functionality
for another part (for example, a wingnut for a hex nut).
1. Remove the two
104136 boom knobs
from the underside of
the 108507 boom.
You will re-use the
knobs in step 7.
5.0 Mounting a Model 3106 Series Antenna
The following steps to mount a Model 3106B Double-Ridged Waveguide Horn
Antenna onto a 108507 boom apply to all Model 3106 Series antennas.

2. Lift the mount adapter
up and away from the
boom.
3. Remove the wingnut to
free the 1/4–20 screw
from the mount adapter.
You will re-use the screw
in step 6.
4. Remove the nuts to
free the two screws
from the vertical plate
on the mount adapter.
You will re-use the
screws in step 6.

Retain these two screws for future use; if you remove the
Model 3106B from the 7-TR, you will need to replace these screws to
provide support for the inner ridge of the antenna.
5. On the side of the
Model 3106B with the
antenna connector,
remove the two
screws from the mount
plate.

information in the ETS-Lindgren
Product Information Bulletin included with
your shipment.
If using a Model 7-TR with pneumatic polarization, test the air
polarization speed prior to mounting an antenna. For the steps to
adjust air polarization speed, see page 46.
To reduce stress and deflection, attach the antenna as close to the
carrier as possible.
7.0 Operation
General Antenna Mounting Information
ETS-Lindgren antennas can be attached to the boom on the Model 7-TR Tripod
Positioner using either the 104136 or 104169 boom antenna mount knob. The
boom includes mounting holes for attaching antennas.

Damage to the antenna may occur if the air
polarization speed is set too high. Adjust the
flow control valves to prevent damage.
Using the Pneumatic Polarization Option
ADJUSTING AIR POLARIZATION SPEED
Flow control valves attached to the air cylinder allow variable speed on
polarization cycling. Use a small screwdriver to adjust the air flow through the
two 90-degree fittings.
