About This Assembly
Specs Summary
RG142 Cable
RG-142 is a double-shielded 50-ohm PTFE coaxial cable rated for operation from cryogenic temperatures up to +200°C with a 0.195" outer diameter. Its dual-shield construction provides excellent EMI rejection while the PTFE dielectric ensures stable electrical performance across a wide frequency range. The preferred choice for military, aerospace, and high-power RF applications.
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.
N Connector
Type N is a threaded RF connector rated from DC to 18 GHz with a durable weatherproof design, making it the preferred interface for outdoor antenna installations, cellular base stations, and commercial wireless infrastructure. Its larger size compared to SMA allows higher power handling and the threaded coupling resists vibration, making it suitable for mobile and fixed outdoor applications.
Common Applications
This FME and N cable assembly is well suited for high-temperature and high-power military or aerospace RF assemblies. The combination of reliable FME and N 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 RG142 coaxial cable used for?
RG-142 is a double-shielded 50-ohm PTFE coaxial cable rated for operation from cryogenic temperatures up to +200°C with a 0.195" outer diameter. Its dual-shield construction provides excellent EMI rejection while the PTFE dielectric ensures stable electrical performance across a wide frequency range. The preferred choice for military, aerospace, and high-power RF applications.
What is the signal loss of RG142?
At 1800 MHz, RG142 has approximately 18.5 dB of loss per 100 ft (0.185 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.
