Specs Summary
About This Assembly
RG316DS Cable
RG-316DS is a double-shielded version of RG-316, featuring two braid layers over the PTFE dielectric for superior EMI isolation. This construction reduces signal leakage and interference pickup, making it essential in sensitive receiver chains, spectrum analyzers, and high-density RF wiring where crosstalk must be minimized.
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.
TNC Connector
TNC (Threaded Neill–Concelman) is the threaded version of BNC, offering improved performance up to 11 GHz and better vibration resistance through its screw coupling. It is commonly used in mobile radio antennas, avionics, and outdoor installations where BNC's bayonet lock would not provide sufficient mechanical security.
Common Applications
This SMA and TNC cable assembly is well suited for sensitive receiver chains, spectrum analyzer inputs, and high-EMI environments. The combination of reliable SMA and 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 RG316DS coaxial cable used for?
RG-316DS is a double-shielded version of RG-316, featuring two braid layers over the PTFE dielectric for superior EMI isolation. This construction reduces signal leakage and interference pickup, making it essential in sensitive receiver chains, spectrum analyzers, and high-density RF wiring where crosstalk must be minimized.
What is the signal loss of RG316DS?
At 1800 MHz, RG316DS has approximately 26 dB of loss per 100 ft (0.26 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.
