UHF Connectors

UHF connector is one kind of RF connector. UHF connector is designed to have thread coupling. Besides, UHF connector series are available for RF cable type and PCB type. UHF connector commonly is used for 0~300MHz.

Wellshow Technology manufactures various UHF connectors and custom UHF RF cable assemblies in Taiwan. We can provide good quality UHF connector in short time and welcome OEM or customized RF connector. Contact us by email or call us 886-2-24270488 to start business!

UHF Connector Series

All UHF Connector

UHF Plug Connector

UHF Jack Connector


UHF connectors feature a threaded coupling with non-constant impedance. The same thread 5/8”-24 as N connector, but UHF jack has notched edges and corresponding lugs on the plugs, which guarantee a high degree of torsion protection and very high vibration security.

The main application is in mobile devices and the preferred frequency is from 0 to 300 MHz.
