RF-Elements STH-A45-USMA Asymmetrical Antenna StarterHorn, 45°, USMA, 5GHz, 17dBi
| Sector 5GHz 45° Gain: 17 dBi |
StarterHorn™ 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.
