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.
TNC Connector
TNC (Threaded Neill–Concelman) is the threaded version of BNC, offering improved performance up to 11 GHz and better vibration resistance through its screw coupling. It is commonly used in mobile radio antennas, avionics, and outdoor installations where BNC's bayonet lock would not provide sufficient mechanical security.
Common Applications
This TNC and UHF cable assembly is well suited for medium-length cellular and WiFi antenna runs at a value price point. The combination of reliable TNC and 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.

| 900 MHz | 7.8 dB | 0.078 dB |
| 1.8 GHz | 11.3 dB | 0.113 dB |
| 2.4 GHz | 13.1 dB | 0.131 dB |
| 5.8 GHz | 21.5 dB | 0.215 dB |
Frequently Asked Questions
What is RFC240 coaxial cable used for?
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.
What is the signal loss of RFC240?
At 1800 MHz, RFC240 has approximately 11.3 dB of loss per 100 ft (0.113 dB/ft).
What frequency range does this assembly support?
This assembly is rated DC – 300 MHz, limited by the lowest-rated component across the cable and connectors.
What is a 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.
