1.0 Introduction

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 26 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.

Model 3142E shown in vertical polarization

Introduction | 7

Model 3142E shown in horizontal polarization

The Model 3142E includes a stinger mount; it also includes a mounting bracket

and 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

Mounting Instructions on page 19.

8 | Introduction

Tripod Options

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.

ETS-Lindgren offers the following non-metallic, non-reflective tripods for use at

both indoor and outdoor EMC test sites.

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 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

Assembly Instructions | 15

Attach Bowtie Elements

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.

The Model 3142E ships with the bowtie elements detached. To attach the bowtie

elements:

16 | Assembly Instructions

1. For stability, mount the Model 3142E onto a tripod or tower. See

Do not cross thread this connection or

permanent damage to the bowtie element could

occur.

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.

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.

18 | Assembly Instructions

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 3142E antenna is a precision

measurement device. Handle with care.

Photos of bowtie elements used in this section may differ from the

bowtie elements for your Model 3142E; the mounting procedure is the

same for both.

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.

Mounting Instructions | 19

Using Included 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

In addition to the attached mounting bracket and mounting knobs, the

Model 3142E ships with these mounting adapters:

20 | Mounting Instructions

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

Do not cross thread or permanent damage to the adapter and

thread insert could occur.

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.

Mounting Instructions | 21

Using the Stinger to Mount to a Model 2175 MiniMast

Do not use the stinger to mount the Model 3142E onto a 4-TR tripod.

Before you begin:

 Install the center rotate boom (part# 108197) 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

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.

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.

22 | Mounting Instructions

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.

Mounting Instructions | 23

5. Tighten the clamp

knobs on the boom

to secure the

antenna into place.

6.0 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.
