ETS-Lindgren announced the launch of a new series of omnidirectional biconical antennas, Models 3180, 3181 and 3182, for broadband spectrum monitoring. The omnidirectional radiation pattern means the antenna can receive signals from every direction around its axis. In addition, for Models 3180 and 3182, the elements have been optimized to avoid any splitting of the main radiation beam in the elevation cut.
Models 3180 and 3182 are designed to cover the traditional frequency range of EMC measurements, from 30 MHz to 1 GHz. The antennas also cover all of the VHF and part of the UHF bands, making them ideal for spectrum monitoring of FM, TV and some cellular phones. A flexible mounting system accommodates both the classic EMCO block mount and a rear “stinger” mount. Model 3180 is also ideal for free space NSA (FSNSA) testing of fully anechoic chambers. In addition, its small size allows for amplifier harmonic monitoring when testing per IEC 61000-4-3.
Model 3181 is a “mini-bicon” antenna designed primarily for CISPR-16 chamber characterization over the 500 MHz to 18 GHz frequency range. It may also be used for amplifier harmonic measurements per IEC 61000-4-3, EM field surveillance, spectrum monitoring and most wireless bands worldwide. With its low weight design, it is ideal for field measurements when connected to a portable spectrum analyzer. Optional weatherproofing is available for long-term monitoring outdoors.
Vince Rodriguez, ETS-Lindgren’s Senior Principal Antenna Design Engineer, commented, “This new series of antennas complements our multiple-octave broadband products by adding broadband omnidirectional models to our directional antenna line.”
Models 3180, 3181 and 3182 are individually calibrated with actual antenna factors, a signed Certificate of Conformance, and a manual included with every shipment. The antennas are available for immediate delivery with quantity pricing.
