The RF elements StarterHorn A45° USMA is a professional asymmetrical horn antenna offering high performance in the 5 GHz band. It is designed to establish reliable wireless connections in dense urban environments or locations with high user capacity. Thanks to its asymmetrical radiation pattern, it focuses the main lobe on the target while side lobes are near zero, greatly suppressing unwanted interference and noise. This feature makes the antenna an ideal choice, especially for dense access point clusters and challenging conditions. The technical strengths of this antenna lie in its high gain of 17 dBi and narrow, controlled beamwidth. With a 31° horizontal and 30° vertical azimuth beamwidth, it can direct the signal with extreme precision, thereby increasing spectrum efficiency and minimizing the risk of interference from other connections. It offers both a standard RP-SMA female connector and a waveguide port that provides the flexibility to connect directly to many radio devices, ensuring superior compatibility. Additionally, the IP55 protection class and wide operating temperature range from -30°C to +55°C make the antenna resistant to all types of outdoor conditions. The StarterHorn A45° USMA is an excellent choice for point-to-point (PtP) or point-to-multipoint (PtMP) connection scenarios. Its direct compatibility with devices such as Ubiquiti PrismStation or IsoStation makes it a frequent choice for establishing data links in enterprise wireless backhaul lines, campus networks, or security camera systems. The high noise rejection feature provides a significant performance advantage in dense spectrum environments where signal quality and connection stability are critical.
