If you are building a harness for a 50 Ohm system on any of those cable types, this is the plug that matches the line. ## Durability and Field Life Rated for 500 mating cycles — that is the threaded coupling wearing the plating, not the contact beam fatiguing. The nickel body finish resists corrosion in a humid cabinet or outdoor enclosure. Single-port design, so one cable per connector — no daisy-chaining through the body.","metaTitle":"Amphenol RF 031-2381-1 TNC Plug, 50 Ohm, 11 GHz, Right Angle","metaDescription":"Amphenol RF 031-2381-1 TNC plug, male pin, 50 Ohm impedance, rated to 11 GHz.
