Product details

SMA Jack for RG-405 Semi-Rigid Cable

The gold-plated stainless steel body and threaded fastening provide a secure, corrosion-resistant RF interconnect for test equipment, antenna feeds, and instrumentation where the cable run is permanently formed and soldered.

Cable Prep and Termination

This connector is a free-hanging, in-line jack that terminates to RG-405 semi-rigid cable. The kit includes the connector body and one contact; you supply the cable and the soldering iron.

Threaded coupling means the nut must be torqued to spec each time — finger-tight is not enough for a stable RF ground.
