This jack mounts through a bulkhead panel using the front-side nut (the flange is part of the zinc die-cast body, nickel-plated). ## What the 75 Ohm Rating Means for Cable Choice The 75 Ohm impedance tells you this jack is designed for RG-6, RG-59, or similar video/cable-TV coax — not the 50 Ohm RG-58 or LMR-200 the RF bench uses. A 50 Ohm cable on a 75 Ohm connector creates a 0.5 dB mismatch at the junction; at 1 GHz that adds up. If your assembly uses RG-6, the body and center contact geometry are matched to the cable's dielectric and center conductor size. The board lock and isolated features (no DC path from shield to ground unless you solder it) let you keep the cable shield isolated from chassis ground if the system needs it.","metaTitle":"Amphenol 031-71058-1010 BNC Jack, 75 Ohm, 1 GHz, 500 Cycles","metaDescription":"Amphenol 031-71058-1010 BNC jack, 75 Ohm, 1 GHz max, 500 mating cycles.
