Item Type: Lightning Arrester Material: Metal Frequency Range: DC 3GHz Discharge Voltage: DC 90V Impedance: 50 Ohm Insertion Loss: <0.1 dB Vswr: 1.2 Maximum Power: 50W Maximum Surge Voltage Allowed to Pass: 200 mV Throughput Energy: 5 nJ Maximum Current Load: 10A Package List 1 x Lightning Arrester 1Professional: Coaxial UHF lightning arrester (UHF female) socket to socket (UHF female), coaxial cable lightning surge protector. With ground screw connection for easy installation. 2Simple Operation: Coaxial lightning surge protector connects a thick copper wire (8 or 10 gauge) from the grounding screw on the side of the arrester to a ground rod driven into the ground with a minimum length of 3 feet. 3Superior Performance: Lightning arrester with superior construction, reliable broadband performance from DC 3GHz, insertion loss of 0.1dB and VSWR 1.2, replaceable 90V gas tube element with high surge power capability. 4Safety Protection: UHF coaxial lightning surge protector can guard your life, the protector provides extremely low loss for HF VHF UHF other frequency devices. 5Low Consumption: Coaxial lightning surge protector has less than 0.1dB insertion loss. Suitable for CB radios, HAM radio equipment and two way base stations. 6Cautions: The lightning surge protector should be installed as close as possible to the equipment to be protected, usually at the point where the coaxial cable enters the building. It can also be installed near the antenna to provide additional protection.
