StarterHorn STH-30-USMA – 1 new RF elements sector antenna
19. May 2021 VARIA

the StarterHorn STH-30-USMA is a scalar horn antenna with a symmetrical radiation pattern and an RP-SMA interface for easy connectivity. The StarterHorn (TM) 30 USMA is a practical entry-level product for customers who are new to horn antenna technology and want a low initial investment.

StarterHorn (TM) antennas have a symmetrical beam pattern with no sidelobes. The antennas provide excellent noise rejection for high density AP clusters and dense collocations. They offer great performance in an affordable package.

StarterHorn (TM) antennas provide an RP-SMA jack interface for H and V antenna polarizations for connectivity with any third party radio in the market. They also allow the use of UBNT radios with a waveguide connection.

Excellent immunity to interference
The sidelobes of widely used traditional patch array antennas cause noise on unlicensed 5 GHz wireless networks. The StarterHorn (TM) 30 USMA has no side lobes, which ensures efficient use of the spectrum. As a result, your wireless network will not experience much interference.

High radiation efficiency
The beam efficiency (BE) is a side lobe measure with values from 0 to 100%. The higher the BE, the fewer sidelobes an antenna has. StarterHorn (TM) 30 ° USMA has a BE of 92%, which suppresses the vast majority of interference and provides a breakthrough increase in throughput. For reference, the BE of widely used patch array sector antennas rarely exceeds 58%!

Frequency-independent beam width and gain
The main lobe shape and gain of the StarterHorn (TM) 30 USMA do not change with frequency. The antenna performance is very stable over a wide frequency range 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 when switching channels.
