Introduction | 9
Tripod Options
ETS-Lindgren offers the following non-metallic, non-reflective tripods for use at
both indoor and outdoor EMC test sites.
For easy horizontal and vertical polarization, the ETS-Lindgren
Model 7-TR tripod is recommended.
 4-TR Tripod—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). This tripod can support
up to an 11.8 kg (26.0 lb) load.
 7-TR Tripod—Constructed of PVC and
fiberglass components, providing
increased stability for physically large
antennas. The unique design allows for
quick assembly, disassembly, and
convenient storage. Allows several
different configurations, including
options for manual or pneumatic
polarization. Quick height adjustment
and locking wheels provide ease of use
during testing. Maximum height is
2.17 m (85.8 in), with a minimum height
of 0.8 m (31.8 in). This tripod can
support a 13.5 kg (30 lb) load.

Assembly Instructions | 15
4.0 Assembly Instructions
Before connecting any components, follow the
safety information in the ETS-Lindgren
Product Information Bulletin included with your
shipment.
The Model 3143B BiConiLog™ Antenna consists of the following:
 Antenna
 Bowtie elements (2)
 10–32 thumbscrew knobs to attach bowtie elements (2)
 Mounting bracket and mounting knob

16 | Assembly Instructions
Attach Bowtie Elements
Photos of bowtie elements used in this section may differ from the
bowtie elements for your Model 3143B; the assembly procedure is the
same for both.
The Model 3143B ships with the bowtie elements detached. To attach the bowtie
elements:

Assembly Instructions | 17
1. For stability, mount the Model 3143B onto a tripod or tower. See
Mounting Instructions on page 19 for the steps to mount the antenna.
2. Slide the narrow end of one of the bowtie elements into the
receptacle hole on the antenna balun, and then align the bowtie with
the receptacle on the balun.
Do not cross thread this connection or
permanent damage to the bowtie element could
occur.
3. Insert one of the 10–32 thumbscrew knobs into the opposite side of the
balun from where you inserted the bowtie. Slowly tighten the knob,
taking care not to cross thread the connection.
4. Repeat steps 2 and 3 for the second bowtie element.

Mounting Instructions | 19
5.0 Mounting Instructions
Before connecting any components, follow the
safety information in the ETS-Lindgren
Product Information Bulletin included with your
shipment.
The Model 3143B antenna is a precision
measurement device. Handle with care.
Contact with any metal or non-metallic structure can capacitively load the
antenna, which may cause unrepeatable results. Therefore, make sure that no
part of the dipole elements or bowties is in contact with the tripod or tower,
particularly in vertically-polarized tests. Where possible, run the feed cable
straight one meter or more back from the Model 3143B BiConiLog™ Antenna
before dropping vertically.

20 | Mounting Instructions
Using Included Mounting Adapters
In addition to the attached mounting bracket and mounting knobs, the
Model 3143B ships with these mounting adapters:
 100989 Polarizing Mounting
Adapter with 7/8–14 thread
receptacle
If you need to convert the polarizing
adapter to a 1/4–20 receptacle,
insert the 1/4–20 thread insert into
the polarizing adapter
 105861 1/4–20 Thread Insert
