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.
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.
UHF Connector
The UHF connector (also known as PL-259 male / SO-239 female) is a large, low-cost RF connector designed in the 1930s for HF and VHF frequencies. Despite its name, its practical usable range is below 300 MHz due to its non-constant impedance design. It remains extremely popular in amateur radio (HF through VHF), CB radio, and marine radio applications.
Common Applications
This SMA and UHF cable assembly is well suited for instrumentation leads, test equipment interconnects, and flexible antenna pigtails. The combination of reliable SMA and UHF 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 – 300 MHz, limited by the lowest-rated component across the cable and connectors.
What is a 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.
