The 082-5722-RFX: The N-type interface is a threaded, weather-resistant design common in base stations, antenna feeds, and test equipment where a stable RF connection through the UHF band is needed. This is the cable-end plug — the free-hanging, cap-style body goes on the coax, not the panel. The brass body gets a nickel finish, and the centre pin is gold-plated brass, which keeps contact resistance low and resists corrosion in outdoor or repeated-mate environments.
If your system is built around 75 Ohm video or broadcast gear, this plug is the wrong match; you would need an N-type variant rated for 75 Ohms. For a 50 Ohm line, the 082-5722-RFX keeps the signal path impedance constant through the connector, minimising reflections and VSWR rise at the junction.
