RF elements asymmetrical StarterHorn A45 - STH-A45-USMA

The RF elements STH-A45-USMA asymmetrical StarterHorn A45 has both RP-SMA and waveguide making it widely compatible with manufacturer radios. 

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°.

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%!
