Omni-Directional Antennas Target Broadband Spectrum Monitoring

 

Models 3180, 3181, and 3182 from ETS-Lindgren are a series of omni-directional, biconical antennas for monitoring broadband spectrum. In addition to receiving signals from every direction around the antenna axis, Models 3180 and 3182 feature optimized elements that forestall any splitting of the main radiation beam in the elevation cut. Models 3180 and 3182 cover the … [Read more...]
