TNC Straight Solder / Top Hat Clamp Plug


TNC 75 ohm straight clamp plug with gold plated soldered centre contact. Suitable for RG59 or similar cables in group AI.

TNC connectors are a screw lock coupling version of the BNC connectors.  The screw coupling enables TNC to be used at frequencies up to 11GHz in harsh environment situations.  Widely used for antenna connections, TNC have many applications in avionics, defence, communications and general industrial markets.  Reverse polarity and 75 ohm TNC are also available.
