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.

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.
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.
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.
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.
