The QRH20EC from RF SPIN is a Quad-Ridged Horn Antenna that operates from 1.7 to 20 GHz. This dual-linear and circularly-polarized antenna can handle an input power of 20 W (CW) and 40 W (peak), provides an isolation of - 33 dB, and has a VSWR of 2.4:1. It is calibrated to cover all the 5G frequency bands and operates over a wide bandwidth with low return loss and an antenna factor of 28 - 42.5 dBm. This horn antenna’s design is improved with a 3D printed patented antenna lens technology that increases the gain while maintaining a 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, ensuring protection in corrosive environments, and is available in a standard housing that measures 101 x 178 x 101 mm with 2.92 mm SMA coaxial connectors. This antenna is ideal for EMC/EMI applications.
