PL-259 Lightning Surge Protector UHF Lightning Arrestor PL259 Female to SO239 Female Bulkhead for CB Ham Base Antennas

UHF Lightning Arrester, PL259 (UHF female) to SO239 socket (UHF female), PL-259 lightning surge protector for coaxial cable. Features a ground screw connection for easy installation. High-quality construction with reliable wide-band performance from DC to 1 GHz, insertion loss of 0.1 dB, and VSWR of 1.2. Contains a replaceable 90V gas tube element with high surge power capability. For installation, run a piece of heavy gauge copper wire (8 or 10 gauge) from the grounding screw on the side of the arrester to a 3-foot minimum length grounding rod driven into the ground.

This PL259 arrester protects HF/VHF/UHF and other frequency equipment with extremely low loss, boasting an insertion loss of less than 0.1 dB. UHF arresters should be installed as close as possible to the equipment to be protected, often at the point where the coax cable enters the building. They can also be installed near the antenna for additional protection
