About This Assembly
Specs Summary
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.
BNC Connector
BNC (Bayonet Neill–Concelman) is a quick-connect RF connector featuring a bayonet locking mechanism for fast mating and unmating, rated from DC to 4 GHz. Its ease of use makes it standard in test and measurement equipment, video distribution, two-way radio accessories, and laboratory bench setups where cables are frequently connected and disconnected.
RP-TNC Connector
RP-TNC (Reverse Polarity TNC) uses the TNC threaded shell with reversed pin conventions, similar to RP-SMA. It is used on some commercial WiFi access points and outdoor CPE antennas, particularly in older Cisco and Linksys equipment, and offers better vibration resistance than RP-SMA in demanding outdoor environments.
Common Applications
This BNC and RP-TNC cable assembly is well suited for medium-length cellular and WiFi antenna runs at a value price point. The combination of reliable BNC and RP-TNC 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.
