Type UHF product is one kind of video frequency coaxial connectors with screw coupling and adopt tooth of end gearing. Impedance is not strict definite, 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.
Yangzhou Jingcheng Electronics Co., Ltd., a premier China UHF RF Coaxial Connectors Manufacturer and UHF RF Coaxial Connectors Factory, was founded in 1999. It is a high-tech enterprise specializing in the R&D and manufacturing of RF coaxial connectors, cable assemblies, and passive microwave components. Equipped with a comprehensive R&D and production system, the company has obtained international certifications including ISO9001. Adhering strictly to standards such as MIL, IEC and GB, we offer over 30 product series with more than 2,000 specifications, covering SMA, BNC, N-type and other mainstream models. Our products are widely applied in the fields of communications, aerospace, automotive electronics and beyond, and exported to many countries and regions across Europe, America and Asia. We uphold the tenet of "Quality as the Foundation, Customers as the Core", committed to providing reliable interconnection solutions and professional services for global clients.
UHF RF coaxial connectors are large-body, threaded connectors used to join flexible cable to radio transceivers, antennas, and base equipment operating at lower RF frequencies. Despite the name, UHF RF coaxial connectors are rated for use up to roughly 300MHz rather than the UHF band itself, a naming convention carried over from early radio equipment. Their coupling nut and solder cup construction make them straightforward to terminate and reliable under repeated mating cycles, which keeps the series in wide use across amateur radio, marine, and land mobile systems.
The category covers straight plugs, bulkhead jacks, and right-angle variants, giving UHF RF coaxial connectors a standard interface across transceivers, antenna feed points, and patch panels built to the same mating dimensions.
Because the shell and pin dimensions have remained unchanged for decades, UHF RF coaxial connectors also remain compatible with a wide installed base of existing radio equipment, simplifying replacement and repair on systems already in service.
The center pin and outer shell form a coaxial signal path, with the shell also acting as the ground return and shield. Unlike connectors built to a constant-impedance profile, the dielectric section of a UHF connector has a stepped diameter, so impedance shifts somewhat with frequency; this has little effect below 300MHz but limits use at higher frequencies where precise impedance matching matters.
A threaded coupling nut secures the plug to the jack, applying steady mechanical retention without a constant-torque requirement. Center conductors are typically soldered into a cup contact, and the outer shell is soldered or crimped to the cable braid, forming a continuous shield path from the cable into the connector body.
Yangzhou Jingcheng Electronics Co., Ltd manufactures UHF RF coaxial connectors and matched cable assemblies under MIL, IEC, and GB standards, supplying radio and communication equipment producers across multiple regions.
Compared with N-type and BNC series, UHF RF coaxial connectors cover a lower frequency range but offer a larger, low-cost solder termination that suits high-current, low-frequency radio equipment rather than precision RF test setups. Where a design calls for constant impedance at higher frequencies, N-type or BNC connectors remain the more suitable choice.
| Parameter | UHF | N-type | BNC |
|---|---|---|---|
| Coupling | Threaded | Threaded | Bayonet |
| Frequency range | DC–300MHz | DC–11GHz | DC–4GHz |
| Impedance control | Non-constant | Constant 50Ω | Constant 50Ω |
| Typical use | Amateur, marine radio | Base stations, test gear | Instrumentation |
The name dates back to early radio equipment. The stepped, non-constant impedance dielectric limits precise performance above roughly 300MHz, even though the shell design was originally associated with UHF-era equipment.
Standard versions are not sealed against moisture, so outdoor or marine installations typically require weatherproofing tape, heat-shrink boots, or a sealed bulkhead variant.
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.
Check first that the coupling nut is fully tightened and the solder joints are intact, then measure standing wave ratio to determine whether the fault lies in the connector or elsewhere in the antenna system.
