SMA Jack for RG-178 — Sealed Bulkhead Mount
It delivers a 50 Ohm impedance path rated to 6 GHz, with a threaded coupling nut for secure mating. The bulkhead front-side nut mounting lets it sit flush against a panel, and the IP67 seal keeps the interface dust-tight and waterproof when mated — unusual for an SMA and a strong signal for outdoor antenna or remote radio head connections.
Cable Termination — RG-178 Specific
This connector is built for RG-178 cable — the cable group is listed explicitly. The centre contact is solder-terminated; the shield is crimped. That means you need the correct crimp die for the RG-178 braid diameter, and the solder joint on the centre pin must be clean to avoid impedance bumps at the transition. The single-port, single-cable design is straightforward for a harness builder.
The closest sibling is the 901-10743 — same SMA jack, same IP67 rating, same 500-cycle gold plating, but cabled for RG-316 Double Braid instead of RG-178. If your BOM calls for RG-316, the 901-10743 is the correct pick; the 901-10742 is specific to RG-178 and the crimp dimensions will not match a larger-diameter cable.
