INTRODUCTION
Model 3142E shown in horizontal polarization
The ETS-Lindgren Model 3142E
BiConiLog™ Antenna is designed
as a dual-purpose antenna that
can be used for both immunity and
emission testing. From 30 MHz to
6 GHz, the Model 3142E exhibits an
average 5.5 dB gain. Applications for
the Model 3142E include emissions
testing, immunity measurements, and
medical equipment testing.
The Model 3142E Antenna includes a stinger mount; it also includes a
mounting bracket and a 1/4–20 thread knob to attach to an ETS-Lindgren
tripod or tower adapter.
For the variety of mounting options available for the Model 3142E, see

Bulletin included with
your shipment.
Note:
Photos of bowtie
elements used in this
section may differ from
the bowtie elements for
your Model 3142E; the
assembly procedure is
the same for both.
ASSEMBLY
The Model 3142E BiConiLog™ Antenna is comprised of the following parts:
• Antenna
• Bowtie elements (2)
• 10–32 thumbscrew knobs to attach bowtie elements (2)
• Mounting bracket and mounting knob
Attach Bowtie Elements
The Model 3142E ships with the bowtie elements detached. To attach the
bowtie elements:

1. For stability, mount the Model 3142E onto a tripod or tower. See Mounting
Instructions on page 19 for the steps to mount the antenna.
Do not cross thread
this connection or
permanent damage
to the bowtie element
could occur.
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.
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.

12
Before connecting any
components, follow
the safety information
in the ETS-Lindgren
Product Information
Bulletin included with
your shipment.
The Model 3142E
antenna is a precision
measurement device.
Handle with care.
Note:
Photos of bowtie
elements used in this
section may differ from
the bowtie elements for
your Model 3142E; the
assembly procedure is
the same for both.
MOUNTING
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 3142E BiConiLog™ Antenna
before dropping vertically.
Using Included Mounting Adapters
In addition to the attached mounting bracket and mounting knobs, the Model
3142E ships with these mounting adapters:
1. 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
2. 105861 1/4–20 Thread
Insert

1312
To attach the included adapters to the Model 3142E:
Model 3142E mounted
onto 4-TR using included
100989 Polarizing Mounting
Adapter and 105861 1/4–20
Thread Insert
1. If required, insert the 1/4–20 thread insert into the mounting adapter.
2. Remove the mounting knob from the mounting bracket on the antenna.
3. Slide the mounting bracket onto the mounting adapter with the adapter
placed between the shoulders of the mounting bracket.
4. Thread the mounting knob through the mounting bracket, then through
the mounting adapter, and finally through the hex nut.
5. Tighten the mounting knob to secure the antenna.
6. Attach the mounting adapter and antenna to tripod or tower, as required.
Using the Stinger to Mount to a Model 2175 MiniMast
The stinger mount provides on-axis rotation during 90° horizontal or vertical
polarization. The stinger enables you to mount the antenna directly to an ETS-
Lindgren 7-TR Tripod or mast.
Before you begin –
• Install the center rotate boom (part# 108507) for rear-mount stinger-type
antennas.
• Attach the included mounting adapter to the Model 3142E as instructed in
Using Included Mounting Adapters on page 20.
• You will need one of the optional mounting knobs described in 7-TR and
Mast Mounting Options on page 26. To order optional mounting hardware,
contact the ETS-Lindgren Sales Department.
Do not cross thread or
permanent damage to
the adapter and thread
insert could occur.
Note:
Do not use the stinger
to mount the Model
3142E onto a 4-TR
tripod.

Before connecting any
components, follow
the safety information
in the ETS-Lindgren
Product Information
Bulletin included with
your shipment.
The Model 3142E
antenna is a precision
measurement device.
Handle with care.
Note:
Photos of bowtie
elements used in this
section may differ from
the bowtie elements for
your Model 3142E; the
assembly procedure is
the same for both.
1. Thread the antenna feed
or receiving cable through
the center of the boom
so that the antenna
connector emerges a few
inches out of the clamp
end of the boom.
2. Attach the cable to the
Type N connector at the
end of the stinger.
3. Slide the cable and
stinger into the clamp
on the boom, carefully
guiding the cable out the
other end.
4. When you reach the back
of the balun box, align it
with the boom receptacle,
and then slide the smaller
portion of the balun box
into the boom. This will
prevent rotation of the
antenna unless the boom
is being polarized.

5. Tighten the clamp knobs
on the boom to secure the
antenna into place.

TYPICAL DATA
Typical Antenna Factor and Gain
Distance for the ANSI 3-meter and 10-meter calibrations is measured from the
antenna midpoint, and for SAE 1-meter calibrations the distance is measured
from the antenna tip. Midpoint is defined as half the distance between the small
elements and the bowties, which is about 45 cm from the small end tip.
