TNC Jack for RG-58 – Bulkhead, Crimp, Weatherproof
The Amphenol 031-6166 is a TNC jack (female socket) rated for 50 Ohm impedance up to 11 GHz, built for bulkhead mounting with a front-side nut. The cable group covers RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, and 9907 — match the body to the reel before you cut the cable.
The 031-6166 is designed for the RG-58 family and its equivalents (LMR-195, Belden 9907). The shield termination is crimp — use the correct die for the ferrule, or the impedance step at the crimp will show up on the VNA.
This jack mounts through a bulkhead panel and secures with a front-side nut, with the included gasket and lockwasher providing a weatherproof seal. The gold-on-phosphor-bronze center contact handles repeated reconnects without fretting, which matters for field-service gear that gets swapped out.
RF Performance
The 500 V voltage rating covers typical RF power levels on these cables. The weatherproof rating means it can live on an antenna or an outdoor enclosure without a secondary boot.
