RF Elements STH-A45-USMA Asymmetrical StarterHorn Antenna

The StarterHorn A45 USMA has unique radiation pattern. The main beam is asymmetrical, with elliptical cross-section: measured at -6dB, the azimuth beam width is 45° and elevation beam width is 30°. Noise in unlicensed 5GHz wireless networks is caused by the side lobes of widely used traditional patch array antennas. The StarterHorn A45 USMA has zero side lobes, ensuring efficient use of the spectrum. As a result, your wireless network does not suffer from high interference. Beam Efficiency (BE) is a side lobes measure with values from 0 to 100%. The higher the BE, the less side lobes an antenna has. StarterHorn A45° USMA has BE of 90%, suppressing vast majority of interference and providing game changing throughput increase. For reference, BE of widely used patch array sector antennas rarely exceeds 58%! The shape of the main lobe and the gain of StarterHorn A45 USMA do not change with frequency. Antenna performance is rock solid stable over a wide span of frequencies between U-NII-1 and U-NII-3 bands. This is extremely important for WISPs planning their network deployments, as they can rely on antenna performance whenever changing a channel.
