About This Assembly
Specs Summary
RFC195 Cable
RFC-195 is a budget-friendly 50-ohm coaxial cable with a 0.195" outer diameter that provides good performance for short-to-medium runs at a lower price than LMR-195. Suitable for antenna jumpers, two-way radio leads, and WiFi access point connections up to 30 feet where cost efficiency is the primary consideration.
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 short-to-medium antenna jumpers and budget wireless installations. 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 RFC195 coaxial cable used for?
RFC-195 is a budget-friendly 50-ohm coaxial cable with a 0.195" outer diameter that provides good performance for short-to-medium runs at a lower price than LMR-195. Suitable for antenna jumpers, two-way radio leads, and WiFi access point connections up to 30 feet where cost efficiency is the primary consideration.
What is the signal loss of RFC195?
At 1800 MHz, RFC195 has approximately 15.1 dB of loss per 100 ft (0.151 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.
