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 optional pedestal Model 113870 (sold separately)
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.

Assembly and Mounting Instructions
Before connecting any components, follow the safety information in the ETS- Lindgren Product Information Bulletin included with your shipment.
Illustration features optional components (sold separately).
The Model 3158 High Power Biconical Antenna is shipped unassembled, and
includes these parts:
- Balun
- Biconical element (2)
- Belleville washer (2)
An optional pedestal, Model 113870, is sold separately
Due to the size of the antenna, you must mount the balun onto the pedestal
before you attach the elements.
-
Run your antenna cable through the polarization tube and attach it to the connector on the bottom of the balun.
Illustration features optional components (sold separately). -
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. -
Slide a belleville washer onto the threaded screw end of one of the biconical elements.
-
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.
-
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.
-
Connect the air solenoid tube to the air solenoid located on the back of the pedestal. Connect the other end to your air supply.
The Model 2090 (or next generation ETS-Lindgren controller, if applicable) is a separate component required for operation. -
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.
