Product details

TNC Plug for RG-179 – 50 Ohm, Crimp, 500 Cycles

The 031-2242-RFX: The threaded coupling provides a secure, vibration-resistant mate, and the nickel-plated brass body with gold-plated centre contact delivers consistent RF performance over 500 mating cycles.

The PTFE dielectric material in the connector matches the cable's dielectric for a consistent 50 Ohm impedance through the junction.

Duty Rating and Environment

Insertion loss is specified at 0.18 dB, which is typical for a TNC plug at lower microwave frequencies and keeps the signal path clean in a short cable run.
