The radiation pattern of StarterHorn™ A45 USMA has asymmetrical main lobe and zero side lobes. StarterHorn™ antennas offer great noise rejection needed for high-density AP clusters and dense co-location.
StarterHorn™ antennas offer both waveguide and RP-SMA female connector interface allowing easy connectivity to any third-party radio on the market, incl direct connectivity to UI radios with an waveguide interface.

StarterHornTM Sector Antenna

STH-A45-USMA is a scalar horn antenna with a asymmetrical radiation pattern. STH-A45-USMA has both waveguide and RP-SMA interface for easy connectivity. The StarterHornTM A45 USMA is a convenient start for customers new to horn antenna technology requesting low initial investment.

Excellent Beam Performance

The StarterHornTM 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°.

Excellent Noise Immunity

Noise in unlicensed 5 GHz wireless networks is caused by the side lobes of widely used traditional patch array antennas. The StarterHornTM A45 USMA has zero side lobes, ensuring efficient use of the spectrum. As a result, your wireless network does not suffer from high interference.

High Beam Efficiency

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. StarterHornTM 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%!

Frequency Independent Beam Width and Gain

The shape of the main lobe and the gain of StarterHornTM 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.

Powerful Co-Location Ability

StarterHornTM A45 USMA delivers excellent performance in dense co-location deployments. You can split poorly performing 90° sector into two 45° sectors with excellent performance using StarterHornTM A45 sector antennas and offer higher throughput packages or connect more customers.

Flexible Connectivity

The StarterHornTM A45 USMA offers a wide range of radio connectivity options. The RP-SMA ports are suitable for any radio with coaxial output. Additional waveguide port enables connectivity to IsoStation and PrismStation radios from Ubiquiti Networks.

Compact and Durable

The StarterHornTM A45 USMA is built using premium materials, yet priced reasonably. Antenna is built of aluminum and therefore very light and compact. Mount is simple and functional with M6 stainless steel hardware.
