FME Connector - The FME connector is designed for a smaller diameter size allowing to be used far better when snaked through a mobile installation or in a tight equipment configuration. The letters FME stand for "For Mobile Equipment" and the connector is 50 Ohm impedance. The thread of the FME connector is 8mm at 0.75mm pitch. FME connectors are also very popular with WiFi equipment.
