About This Assembly

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.

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 SMA cable assembly is well suited for mobile radio setups and flexible medium-length antenna connections. The combination of reliable 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.
