Sanny Telecom 7.125GHz to 8.5GHz ultra high performance microwave dish antennas provide high-gain, low-VSWR radiation patterns, these antennas minimize frequency congestion and simplify frequency coordination due to their highly efficient beam-forming feed assembly. Products feature a customized feed system that allows the antenna to be connected to the 7GHz radios directly or split with the flexible waveguide. They are ideal for the CAMBIUM NETWORKS PTP 7GHz radio and Huawei 7GHz radio series. The whole unit was fully preassembled at the factory to facilitate the complicated installation. The diameters of dish antennas include 2 ft. (60 cm), 3 ft (90 cm), 4 ft. (120 cm), 6 ft. (180 cm), 8ft (240 cm) and 10ft (300 cm).
