Features 1. FEMALE TO FEMALE: Coaxial UHF lightning arrestor (UHF female) socket to socket (UHF female), coaxial cable lightning protection. With ground screw for easy installation. 2. INSTALLATION METHOD: Connect a thick copper wire (8 or 10 gauge) from the ground screw on the side of the lightning arrestor to a ground rod driven into the ground with a minimum length of 3 feet. 3. LOW LOSS: UHF lightning arrestor from DC to 3GHz for reliable broadband performance, insertion loss 0.1dB and VSWR 1.2, replaceable 90V gas tube element with high surge capacity. 4. APPLICABLE: Lightning protection provides extremely low loss HF VHF UHF other frequency equipment. Suitable for CB radios, HAM radio equipment, and two-way base stations. 5. INSTALLATION LOCATION: The lightning arrestor is installed as close as possible to the equipment to be protected, usually at the point where the coaxial cable enters the building, or it can be installed near the antenna to provide additional protection. specification Item Type: Lightning Arrestor Material: Metal Frequency Range: DC to 3GHz Discharge Voltage: DC 90V Impedance: 50 Ohm Insertion Loss:
