MINI UHF RF coaxial connectors are reduced-size, threaded connectors used to join flexible cable to radio equipment where panel space and cable diameter are limited. Built on the same shell and coupling concept as standard UHF connectors, MINI UHF RF coaxial connectors occupy a smaller footprint while covering a comparable frequency range, up to approximately 300MHz. This makes them a fit for handheld radios, compact transceivers, and portable antenna systems where a full-size UHF shell would not clear the enclosure. Straight, right-angle, and panel-mount variants extend the range of MINI UHF RF coaxial connectors across mobile and fixed installations alike.
Common Types & Characteristics
- Straight plug — inline termination onto flexible cable for standard cable-to-radio connections
- Right-angle plug — reduces clearance depth behind the connection point in compact enclosures
- Bulkhead jack — panel-mount version for chassis feedthrough on radio and antenna equipment
- Crimp and solder termination options, selected according to cable type and assembly method
Across these types, the connector shell maintains a threaded coupling nut for secure retention under vibration, while the smaller pin and body diameter keeps overall cable assembly weight and bend radius lower than standard UHF hardware.
Application Scenarios
- Handheld and portable two-way radio antenna connections
- Compact mobile radio installations with restricted mounting space
- Marine and outdoor communication devices requiring lightweight cable assemblies
- Retrofit projects replacing full-size UHF connectors in space-constrained housings
Yangzhou Jingcheng Electronics Co., Ltd manufactures MINI UHF RF coaxial connectors and matched cable assemblies, supplying radio and communication equipment producers with connectors suited to compact device designs.
Selection Points
Choosing the correct connector variant depends on a small number of practical factors rather than frequency alone, since most MINI UHF applications operate well within the connector's rated range.
- Confirm available panel or enclosure depth to choose between straight and right-angle plugs.
- Match termination method — crimp or solder — to the cable type already specified in the design.
- Select bulkhead versions where the connector must pass through an enclosure wall rather than terminate inline.
- Check gasket or sealing requirements for outdoor, marine, or vibration-exposed installations.
Comparison with Related Connectors
Compared with standard UHF and BNC series, MINI UHF RF coaxial connectors trade some mechanical size for board and enclosure space, without a significant change in usable frequency range for typical land mobile and marine radio applications.

Frequently Asked Questions
Are MINI UHF connectors compatible with standard UHF equipment?
No. The reduced shell diameter is not interchangeable with standard UHF connectors, so equipment must be designed or retrofitted specifically for the MINI UHF interface.
Do MINI UHF connectors support outdoor or marine installations?
Standard versions are not sealed against moisture. Gasketed bulkhead variants or additional weatherproofing are recommended for exposed installations.
Can custom cable assemblies be produced with MINI UHF connectors?
Cable assemblies can be configured to cable type, length, and connector combination at each end, based on the equipment interface requirement or an existing sample.
