Antenna lightening arrestor PL 239 -SO 239 for UHF connector for Railways etc

Key Features DESIGNED FOR VHF, UHF, TWO-WAY, AMATEUR / HAM and CB RADIOS - Features 2 UHF Female SO239 Connectors BI-DIRECTIONAL PROTECTION - High Quality Construction - Outdoor Rated - Suitable for In-Line Use VERY LOW RF INSERTION LOSS (Signal Attenuation) - 50 Ohm Impedance - DC Pass-Through 230V GAS DISCHARGE TUBE - Coaxial Cable Surge Protector with Multi-Strike Capability Shunts Damaging Surges, Transients, and Lightning Energy to Ground CONNECT COAXIAL SURGE PROTECTOR to Antenna Signal Feedline and Earth Ground This gas discharge tube lightning suppressor features wide-band operation from DC to 3 GHz with low RF insertion loss, making it ideal for HF, Marine VHF, UHF, CB, Amateur Radio (Ham), P25, GMRS, LMR, Two-Way and other radio system antennas. It can absorb 2.5 times the energy of typical 90V arresters. With UHF-Male (PL-259) and UHF-Female (SO-239) connectors, the arrester connects inline with your existing coax cabling. It passes DC for applications such as remote amplifiers and LNAs. Both ports are equally protected - it can be installed in either orientation. The housing ground lug provides superior grounding. Coaxial lightning suppressors should be installed between outdoor antennas and radio equipment to protect from high-energy electrical pulses carried through the coax cable either from a direct or nearby lightning strike. Arresters should be installed outdoors as close as possible to the equipment to be protected, typically at the point where the coax cable enters the building.
