Description
The FME (For Mobile Equipment) series is a subminiature RF interface specifically designed for applications requiring high-density cable routing and mobile antenna systems. This female (jack) variant is specifically calibrated for LMR240 coaxial cable, a popular low-loss alternative to standard RG8X. The LMR240 cable’s larger 6.1mm diameter offers significantly lower attenuation than thinner cables, and this connector allows users to maintain that performance while utilizing the FME interface’s unique advantage: a slim, cylindrical profile that can be pulled through tight apertures and vehicle conduits.
Maintaining a consistent 50-Ohm impedance, this connector is essential for cellular signal boosters, WiFi extensions, and radio communications. It employs a professional dual-crimp termination system for both the center pin and the outer ferrule, ensuring a gas-tight mechanical bond that resists vibration and environmental stress. Manufactured with a nickel or gold-plated brass body and premium PTFE (Teflon) insulation, it provides excellent electrical stability and shielding effectiveness across VHF, UHF, and cellular frequency bands.
Key Technical Advantages
-
LMR240 Low-Loss Optimization: Specifically designed to accommodate the larger dielectric and jacket dimensions of LMR240, ensuring a seamless electrical transition and minimal VSWR.
-
Slimline Routing Profile: The compact FME interface allows cable assemblies to be routed through narrow access holes or conduits that would obstruct standard-sized connectors.
-
50-Ohm System Integrity: Strictly calibrated to maintain impedance matching, preventing signal reflections and maximizing power transfer in wireless transmission systems.
