Product Description
Type UHF products is one kind of video frequency coaxial connectors with screw coupling and adopt tooth of end gearing. Impedance is not strictly defined, but usually applied at the frequency of 500 MHz. This products are very suitable for the civil wave band communication system, closed-circuit television, the car radio device products etc. these connectors have characteristics of reliable connection, good vibration performance, and reasonable price.
The usage of UHF connector:
- Television broadcasting
- Cordless phones
- Personal radio services satellite communication
- Cell phones
