1.0 Introduction
The ETS-Lindgren Model 3104C Biconical Antenna is designed to operate
over the 20 MHz to 200 MHz frequency range to meet Military and Department of
Defense EMI specifications. The Model 3104C is designed and precisely
manufactured to conform to the requirements of MIL-STD-461 and other Military
Standards as reflected in Drawing ES-F-201286.
The biconical elements are made from welded aluminum. The elements mount in
a balun network fabricated of phenolic and equipped with the necessary
impedance-matching components. The lightweight construction provides easy
handling and storage.
Each antenna is individually calibrated during the manufacturing process. The
results of these calibrations are included for use in specification compliance
testing.

Collapsible folding elements are available, making the Model 3104C portable and
ideal for field use. Both the standard rigid and optional folding elements attach to
the balun using screw mounts. This makes changing between the two types of
elements quick and easy.
