Product details

Mini-UHF Plug for RG-8X-Class Cables

The 081-114-RFX is listed for RG-8X, Belden 9258, and LMR-240 — all roughly 0.195-inch-diameter 50 Ohm cables common in short-run antenna feeds, jumpers, and indoor distribution. The crimp-on shield termination gives a consistent 360° ground bond that a clamp or solder lug cannot match, which matters for keeping the VSWR clean up to 2.2 GHz. The 500 mating cycles rating reflects the gold-plated centre contact; the threaded coupling nut provides vibration-resistant retention once tightened finger-tight plus a quarter turn with a wrench.

Frequently asked questions

Does the 081-114-RFX require a crimp tool?

You need the correct crimp die set for the cable jacket diameter — no soldering required.
