Specifications
UHF Male Angle Connector
UHF Family
The UHF connector (also known as PL-259 male / SO-239 female) is a large, low-cost RF connector designed in the 1930s for HF and VHF frequencies. Despite its name, its practical usable range is below 300 MHz due to its non-constant impedance design. It remains extremely popular in amateur radio (HF through VHF), CB radio, and marine radio applications.
Typical Applications
Amateur (ham) radio HF/VHF/UHF transceivers, CB radio, marine VHF radio, antenna switches and coax relays.
Gender & Polarity Note
This is a Male connector — it has a center pin that inserts into a female socket. Male connectors are used on cable assemblies and pigtails that plug into equipment jacks.
Frequently Asked Questions
What frequency range does the UHF Male Angle connector support?
UHF connectors are rated DC – 300 MHz. The effective upper frequency of a cable assembly is limited by the lowest-rated component — either the cable or the connector. Always verify both are within spec for your target frequency.
How many times can a UHF connector be mated and unmated?
UHF Male Angle connectors are rated for approximately 500 mating cycles. Exceeding this can cause wear on the contact surfaces, increasing insertion loss and VSWR. For applications with very frequent connects and disconnects, consider a connector rated for higher cycle counts.
What torque should I use to tighten a UHF connector?
Use a torque wrench and follow the connector manufacturer's recommended torque specification. Hand-tight plus a quarter turn is a safe starting point for most push-on connectors.
Are the UHF connectors on CoaxRF assemblies weatherproof?
Our standard cable assemblies use high-quality connectors suitable for most indoor and sheltered outdoor applications. For fully weatherproof outdoor installations, we recommend applying self-amalgamating tape over the connector junction to prevent moisture ingress.
Do CoaxRF cables with UHF Male Angle connectors ship assembled and tested?
Yes. Every cable assembly — including those terminated with UHF Male Angle connectors — is hand-assembled and continuity tested before shipping. Cables ship free within the US from our US facility.
