About This Assembly
Specs Summary
LMR240 ULTRA FLEX Times Cable
LMR-240-UltraFlex is the ultra-flexible variant of LMR-240 from Times Microwave, sharing the same electrical performance but with a stranded center conductor and softer jacket that makes it significantly easier to route. Preferred for mobile radio installs, vehicle-mounted antennas, and any application with tight bends or frequent cable movement.
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.
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 SMA and TNC cable assembly is well suited for vehicle-mounted radio installations, tight-routing applications, and mobile platforms. The combination of reliable SMA and 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.
