Comba SP-NFNF7G DC - 7 GHz Coaxial RF Surge Protector with N Female
The Comba SP-NFNF7G is a bulkhead-mount coaxial RF surge protector with N-female connectors on both ends, covering DC to 7 GHz at 50 ohms. It is a DC-pass, bidirectional protector rated for 10 kA surge current (8/20 us waveform) and 150 W average RF power. The IP67 housing is suitable for indoor or outdoor installation, typically in line with the donor antenna feed of a BDA/DAS system.
