Introduction | 7
1.0 Introduction
The ETS-Lindgren Model 3182 Broadband Biconical Antenna is designed for
optimal performance across the frequency range of 30 MHz to 1 GHz. The
uniquely-designed elements provide an omni-directional pattern without the main
radiation beam splitting into two lobes in the elevation cut.
In addition to covering the traditional frequency range EMC measurements, the
Model 3182 covers all the VHF and part of the UHF bands, making it ideal for
spectrum monitoring of FM, TV, and some cellular phones.
The Model 3182 is designed to have a radiation pattern that is dipole-like across
the range. The elements have been optimized to avoid any splitting of the main
radiation beam in the elevation cut.
The Model 3182 is ideal for surveillance and spectrum monitoring. The
omni-directional patterns can receive signal from every direction in the azimuth.
The Model 3182 includes a stinger mount and standard mounting hardware. For
the variety of mounting options available for the Model 3182, see
Mounting Instructions on page 17.

load.
•Model 7-TR—Constructed of PVC
and fiberglass components, providing
increased stability for physically large
antennas. The unique design allows
for quick assembly, disassembly, and
convenient storage. Allows several
different configurations, including
options for manual or pneumatic
polarization. Quick height adjustment
and locking wheels provide ease of
use during testing. Maximum height is
