About This Assembly
Specs Summary
RG316 Cable
RG-316 is a lightweight, flexible 50-ohm PTFE coaxial cable with a 0.100" outer diameter, combining good high-frequency performance with excellent flexibility. Silver-plated copper conductors and PTFE dielectric allow reliable operation from DC to 3 GHz and beyond. Widely used in instrumentation, test equipment, and antenna pigtails where flexibility and moderate power handling are needed.
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 instrumentation leads, test equipment interconnects, and flexible antenna pigtails. 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.

Frequently Asked Questions
What is RG316 coaxial cable used for?
RG-316 is a lightweight, flexible 50-ohm PTFE coaxial cable with a 0.100" outer diameter, combining good high-frequency performance with excellent flexibility. Silver-plated copper conductors and PTFE dielectric allow reliable operation from DC to 3 GHz and beyond. Widely used in instrumentation, test equipment, and antenna pigtails where flexibility and moderate power handling are needed.
What is the signal loss of RG316?
At 1800 MHz, RG316 has approximately 27 dB of loss per 100 ft (0.27 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 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.
