1.0 Introduction

The ETS-Lindgren Model 3158 High Field Biconical Antenna is specifically

designed for Immunity testing.

This linearly-polarized

transmit antenna is

optimized to generate

high levels of

electromagnetic fields in

the range of 20 MHz to

120 MHz.

Model 3158 shown with pedestal

The ability of the Model 3158 to handle high power levels over a broadband

makes it excellent for use in Radiated Susceptibility testing.

The biconical elements are made from welded aluminum tubing. The 4-to-1 ratio

balun network is fabricated from G10 fiberglass and specially machined brass

and aluminum support and contact parts. The bifilar inductors of the balun are

wound in precision-machined cuts to provide high barrier insulation between

windings while simultaneously giving good coupling between bifilar windings.

During manufacturing each Model 3158 is individually calibrated using the

three antenna method of calibration. The results of the calibration are tabulated

and included with the antenna.

following guidelines.

9 | Maintenance

Before performing any maintenance, disconnect
the fiber optic cables from the unit and turn off
power.

When disconnecting fiber optic cables, apply
dust caps to the ends to maintain their integrity.

Before connecting fiber optic cables, clean the
connector tips.

Before attaching connectors, clean them with
moisture-free compressed air.

Failure to perform these tasks may result in
damage to the fiber optic connectors or cables.

4.0 Assembly and Mounting Instructions

Before connecting any components, follow the
safety information in the ETS-Lindgren
Product Information Bulletin included with your
shipment.

13 | Assembly and Mounting Instructions

The Model 3158 High Power Biconical Antenna is shipped unassembled, and

includes these parts:

• Balun

• Biconical element (2)

• Pedestal

• Belleville washer (2)

• Washer (4) and 5/16–1 1/4 hex bolt (4)

• Air solenoid nylon tube

• Fiber optic polarization cable

Due to the size of the antenna, you must mount the balun onto the

pedestal before you attach the elements.

1. Run your antenna cable through the polarization tube and attach it to

the connector on the bottom of the balun.

Assembly and Mounting Instructions | 14

2. Place the bottom of the balun in the mount plate. Insert two washers

and two hex bolts on both sides of the mount plate to firmly secure the

balun in place.

Do not cross thread any connections or
permanent damage could occur.

3. Slide a belleville washer onto the threaded screw end of one of the

biconical elements.

4. Line up the screw threads on the element with the receptacle hole on

the balun and turn the element until it is firmly secured in the balun.

5. Repeat step 3 and step 4 for the remaining biconical element.

Damage to the pneumatic system may occur if
the air supply exceeds the maximum
50 psi–70 psi.

6. Connect the air solenoid tube to the air solenoid located on the back of

the pedestal. Connect the other end to your air supply.

15 | Assembly and Mounting Instructions

The Model 2090 (or next generation ETS-Lindgren controller, if

applicable) is a separate component required for operation.

7. Connect the fiber optic polarization cable to the polarization unit

located on the back of the pedestal. Connect the other end to the

Model 2090 Multi-Device Controller.
