That 75 Ohm impedance matches it to video, broadcast, and telecom cable systems like AT&T 735, 735A, and Belden 735A1. Bayonet lock secures the mate — a quarter-turn and it's locked, no tool needed. The cable group compatibility is specific: AT&T 735, 735A, and Belden 735A1. Those are 75 Ohm coax cables with a nominal impedance that matches the connector. Using a different cable changes the impedance at the crimp point and degrades the return loss. ## Durability and Termination The brass body with nickel finish gives a corrosion-resistant shell that grounds through the bayonet lock.","metaTitle":"Amphenol 031-70240 BNC Plug Kit, 75 Ohm, 4 GHz, 500 Cycles","metaDescription":"Amphenol 031-70240 BNC plug kit, 75 Ohm impedance, 4 GHz max, 500 mating cycles.
