Introduction 

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.
