Features 1. MODEL: Coaxial UHF lightning arrester (UHF male) socket to socket (UHF male), coaxial cable lightning surge protector. With ground screw connection for easy installation. 2. HIGH PERFORMANCE: UHF lightning arrester from DC to 3GHz for reliable broadband performance, insertion loss 0.1dB and VSWR 1.2, replaceable 90V gas tube element with high surge power capability. 3. APPLICABLE OBJECTS: UHF coaxial lightning arrester provides extremely low loss protection for HF, VHF, UHF and other frequency equipment. Suitable for CB radios, HAM radio equipment and two-way base stations. 4. INSTALLATION LOCATION: Lightning arrester should be installed as close as possible to the equipment to be protected, typically where the coaxial cable enters the building, or near the antenna for additional protection. 5. 1/4 WAVELENGTH: Theory and practice have proven that the transmit and receive conversion efficiency of an antenna is higher when the length of the antenna is 1/4 of the radio signal wavelength. Specification Item Type: UHF Lightning Arrester Material: Metal Frequency Range: DC to 3GHz Discharge Voltage: DC 90V Impedance: 50 Ohm Insertion Loss: ≤0.1dB
