About This Assembly
Specs Summary
LMR240 Times Cable
LMR-240 is a Times Microwave 50-ohm low-loss coaxial cable with a 0.240" outer diameter and excellent flexibility for its size. Designed for medium-length runs up to 75 feet, it is widely deployed in cellular infrastructure, public safety radio, GPS distribution, and anywhere a balance of low loss and easy installation is required.
QMA Connector
QMA is a quick-mate RF connector that provides the electrical performance of Type N up to 18 GHz with a faster quarter-turn locking mechanism instead of full threading. It is widely deployed in cellular base station cabinets, DAS installations, and equipment racks where rapid cable changes are required without sacrificing electrical performance.
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 QMA and SMA cable assembly is well suited for medium-length antenna runs, public safety radio, and cellular infrastructure jumpers. The combination of reliable QMA 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.
