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.
RP-SMA Connector
RP-SMA (Reverse Polarity SMA) uses the SMA threaded coupling mechanism but with the male/female pin convention reversed — the jack has a pin and the plug has a socket. Originally standardized to prevent connection of uncertified antennas to consumer WiFi equipment, RP-SMA is now the dominant connector on commercial WiFi routers, access points, and 2.4/5 GHz antennas.
RP-TNC Connector
RP-TNC (Reverse Polarity TNC) uses the TNC threaded shell with reversed pin conventions, similar to RP-SMA. It is used on some commercial WiFi access points and outdoor CPE antennas, particularly in older Cisco and Linksys equipment, and offers better vibration resistance than RP-SMA in demanding outdoor environments.
Common Applications
This RP-SMA and RP-TNC cable assembly is well suited for instrumentation leads, test equipment interconnects, and flexible antenna pigtails. The combination of reliable RP-SMA and RP-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.

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 RP-SMA connector?
RP-SMA (Reverse Polarity SMA) uses the SMA threaded coupling mechanism but with the male/female pin convention reversed — the jack has a pin and the plug has a socket. Originally standardized to prevent connection of uncertified antennas to consumer WiFi equipment, RP-SMA is now the dominant connector on commercial WiFi routers, access points, and 2.4/5 GHz antennas.
