About This Assembly
Specs Summary
RFC240 ULTRA FLEX Cable
RFC-240-UltraFlex is the flexible version of RFC-240, combining low-loss 0.240" performance with improved bendability for easier installation. Ideal for mobile radio setups, vehicle antenna mounts, and congested equipment areas where a rigid cable would be impractical.
N Connector
Type N is a threaded RF connector rated from DC to 18 GHz with a durable weatherproof design, making it the preferred interface for outdoor antenna installations, cellular base stations, and commercial wireless infrastructure. Its larger size compared to SMA allows higher power handling and the threaded coupling resists vibration, making it suitable for mobile and fixed outdoor applications.
SMA Connector
SMA (SubMiniature version A) is the most widely used RF connector in the industry, offering a threaded interface that provides a secure, low-reflection connection from DC to 18 GHz. Its compact size, 50-ohm impedance, and broad frequency range make it the default choice for WiFi equipment, software-defined radios, cellular antennas, GPS receivers, and RF test instruments.
Common Applications
This N and SMA cable assembly is well suited for mobile radio setups and flexible medium-length antenna connections. The combination of reliable N and SMA 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.

Frequently Asked Questions
What is RFC240 ULTRA FLEX coaxial cable used for?
RFC-240-UltraFlex is the flexible version of RFC-240, combining low-loss 0.240" performance with improved bendability for easier installation. Ideal for mobile radio setups, vehicle antenna mounts, and congested equipment areas where a rigid cable would be impractical.
What is the signal loss of RFC240 ULTRA FLEX?
At 1800 MHz, RFC240 ULTRA FLEX has approximately 11.7 dB of loss per 100 ft (0.117 dB/ft).
What frequency range does this assembly support?
This assembly is rated DC – 6 GHz, limited by the lowest-rated component across the cable and connectors.
What is a N connector?
Type N is a threaded RF connector rated from DC to 18 GHz with a durable weatherproof design, making it the preferred interface for outdoor antenna installations, cellular base stations, and commercial wireless infrastructure. Its larger size compared to SMA allows higher power handling and the threaded coupling resists vibration, making it suitable for mobile and fixed outdoor applications.
