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.
FME Connector
FME (For Mobile Equipment) is a miniature threaded RF connector designed for mobile and vehicle-mounted antenna applications, particularly at GSM, CDMA, and FM frequencies. Its small size and robust threaded coupling make it common on vehicle-mount antenna mounts, cellular signal boosters, and mobile broadband modems.
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.
Common Applications
This FME and RP-SMA cable assembly is well suited for sensitive receiver chains, spectrum analyzer inputs, and high-EMI environments. The combination of reliable FME and RP-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 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 – 2 GHz, limited by the lowest-rated component across the cable and connectors.
What is a FME connector?
FME (For Mobile Equipment) is a miniature threaded RF connector designed for mobile and vehicle-mounted antenna applications, particularly at GSM, CDMA, and FM frequencies. Its small size and robust threaded coupling make it common on vehicle-mount antenna mounts, cellular signal boosters, and mobile broadband modems.
