TNC Plug for RG-55/142A/400 — 11 GHz, 50 Ohm, Crimp Assembly
The 031-2367-RFX: Rated for 50 Ohms nominal impedance and a max frequency of 11 GHz, it covers the L-band through X-band without breaking a sweat. The threaded coupling gives a positive lock that won't back off under vibration, and the 0.18 dB insertion loss at 11 GHz tells you the interface is clean.
This plug is built for RG-55, 142A, and 400 cable groups — the crimp body and ferrule are sized to match those jacket diameters and dielectric cores. Both the shield and center contact are crimp-terminated, which means you get a repeatable, tool-controlled assembly without soldering.
RF Performance and Mechanicals
At 11 GHz max and 0.18 dB insertion loss, this TNC plug sits above the BNC variants in the same catalog — compare it to the 31-320-RFX (BNC, 4 GHz, 0.2 dB) or the 31-315-RFX (BNC, 4 GHz, 0.2 dB). The threaded interface is what buys you the extra frequency headroom; the BNC bayonet locks start to wobble above 4 GHz.
