SMA Jack for RG-174/316 — 20 GHz, Bulkhead Kit
The SMA-J-C-H-ST-BH1 comes as a complete kit with the connector body, a crimp ferrule, a lockwasher, and a nut — four pieces total. The connector is designed for RG-174 and RG-316 coaxial cable, with a solder contact termination and a crimp shield termination. The gold-plated brass body and gold centre contact keep corrosion at bay in field-service environments.
What the 20 GHz and 50 Ohm Ratings Mean for Your RF Path
The 20 GHz maximum frequency and 50 Ohm nominal impedance suit standard RF signal chains. The 20 GHz ceiling covers most microwave bands up through Ku-band.
Kit Contents and Cable Fit
The kit includes the SMA jack, a crimp ferrule, a lockwasher, and a nut — everything needed for a bulkhead mount. The cable group is RG-174 and RG-316, both 50-Ohm coax with a nominal 0.110-inch diameter. The crimp shield termination gives a solid ground connection to the bulkhead, and the lockwasher prevents the nut from backing off under vibration. The threaded fastening ensures a repeatable mate with any standard SMA plug.
