Broadband Microwave Horn Antenna 3โ4 GHz RHCP 20 dBi 50 Ohm SMA 0.7 kg Directional Wireless Telemetry
The Broadband Microwave Horn Antenna 6.0?7.0GHz (RHCP/LHCP) is a professional high-performance RF antenna designed for stable and precise wireless communication in the upper microwave frequency range. Covering a wide 1GHz operating band, this antenna ensures low-loss, high-gain signal transmission for a broad variety of Wi-Fi, telemetry, SDR, and test systems.
With a gain of 18.5dBi, VSWR < 1.5, and 50-Ohm impedance, the antenna delivers exceptional directivity and low reflection across the entire 6?7GHz band. The dual circular polarization (RHCP and LHCP) design guarantees stable signal reception regardless of device orientation, making it ideal for dynamic environments, drone links, or mobile telemetry systems.
The horn-type design provides clean radiation characteristics with minimal side lobes, ensuring focused and efficient signal transfer. Its broadband performance makes it compatible with various microwave transmitters, receivers, analyzers, and RF test setups operating within the C-band range.
Built from lightweight and durable engineering plastic, the antenna offers mechanical stability and weather resistance while weighing only 360 g. Compact dimensions (160 ร 140 ร 255 mm) make it easy to mount on tripods, masts, or lab stands. Supporting up to 50 W of input power, it?s ready for both laboratory and field applicationsThe Broadband Microwave Horn Antenna 3.0โ4.0 GHz RHCP is a professional directional antenna designed for long-range and interference-resistant microwave communication. Covering the 3 GHz to 4 GHz C-band, it delivers excellent performance for telemetry, wireless data transfer, and radio-relay applications that demand stability, range, and precision.
With a high gain of 20 dBi, 50 Ohm impedance, and low VSWR, the antenna efficiently focuses energy in a narrow beam, providing high signal strength and minimal losses over long distances. The right-hand circular polarization (RHCP) minimizes multipath interference and polarization mismatch, ensuring a clear and consistent connection even in reflective or obstructed environments.
The horn-type design offers superior directionality and frequency consistency across a broad 1 GHz bandwidth, making it an excellent choice for both fixed and portable RF systems. Its lightweight plastic housing (0.7 kg) combines mechanical strength with easy installation and weather resistance. The SMA-female connector provides reliable compatibility with most telemetry receivers, repeaters, SDR modules, and laboratory equipment.
Whether used for industrial wireless networks, measurement systems, or microwave testing setups, this antenna guarantees stable and efficient operation with durable construction suitable for indoor and outdoor use.
