The QRH40C from RF SPIN is a Quad-Ridged Horn Antenna that operates from 4 to 40 GHz. This dual-linear and circularly-polarized antenna can handle an input power of 10 W (CW) and 20 W (peak), provides an isolation of 28 dB, and has a VSWR of 1.4:1. It is calibrated to cover all the 5G frequency bands and operates over a wide bandwidth with low return loss. This horn antenna’s design is improved with a patented antenna lens technology that increases the gain by up to 20 dB while maintaining small size and low weight. It is manufactured using RF Spin’s SPM technology to achieve the best mechanical and radio parameters. This antenna is coated with a corrosion-resistant material, thereby ensuring protection in corrosive environments. It is available in a standard housing that measures 53 x 90 x 53 mm with 2.92 mm connectors.
