The housing color is listed as silver and white, consistent with the nickel body and white dielectric insert visible at the mating face.","metaTitle":"Amphenol RF 031-71058 BNC Jack, 75 Ohm, 1 GHz, Panel Mount","metaDescription":"Amphenol RF 031-71058 75 Ohm BNC jack, female socket, 1 GHz max frequency, 500 V rating, panel mount with bayonet lock.
