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.
BNC Connector
BNC (Bayonet Neill–Concelman) is a quick-connect RF connector featuring a bayonet locking mechanism for fast mating and unmating, rated from DC to 4 GHz. Its ease of use makes it standard in test and measurement equipment, video distribution, two-way radio accessories, and laboratory bench setups where cables are frequently connected and disconnected.
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.
Common Applications
This BNC and FME cable assembly is well suited for sensitive receiver chains, spectrum analyzer inputs, and high-EMI environments. The combination of reliable BNC and FME 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
Is this cable hand-assembled in the USA?
Yes. Every CoaxRF cable assembly is hand-terminated and continuity tested at our US facility before shipping. We do not drop-ship pre-made cables from overseas — each cable is built to order.
Can I order a different length than 50 ft?
Yes. This page is for the 50 ft assembly. Use the length buttons above to select a different standard length, or use the Cable Builder for any custom length.
How much signal loss will I see with this 50 ft cable?
At 1800 MHz, RG316DS loses approximately 26 dB per 100 ft. This 50 ft assembly will have roughly 13 dB of insertion loss at that frequency. See the signal loss table for all frequency points.
What is the maximum frequency for this assembly?
This assembly is rated DC – 2 GHz. The effective frequency limit is set by the lowest-rated component — either the cable or one of the connectors. Both BNC FEMALE and FME FEMALE connectors must be within spec at your target frequency.
What is your return policy?
We accept returns within 30 days of delivery. Custom-length cables are accepted as long as they are in original condition. Contact us and we will provide a prepaid return label at no charge.
