About This Assembly

RFC240 Cable

RFC-240 is a 0.240" 50-ohm low-loss coaxial cable delivering performance comparable to LMR-240 at a more accessible price, making it popular for installers who need reliable medium-distance cable runs. Well suited for cellular repeater installations, point-to-point wireless links, and access point feedlines up to 75 feet.

UHF Connector

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.

Common Applications

This UHF cable assembly is well suited for medium-length cellular and WiFi antenna runs at a value price point. The combination of reliable UHF connectors and custom-cut cable length makes it a practical choice for both field installations and bench setups. Every assembly is hand-terminated, continuity tested, and ships free within the USA.
