It is of a similar caliber to the mini-UHF connector and is used as a more modern alternative in similar applications.įME connector antennas deliver reliable performance for both static and mobile applications as its threaded connection is secure, stable, and provides high mechanical strength. FME connectors are designed to be fitted to low loss coaxial cable like RG-58, RG-8X RG-174, Belden 7806A, or LMR 195 and the straight connector will provide easier assembly in tight spaces. This slim and compact connector lends itself to several applications as outlined below. These frequencies support cellular and amateur radio connectivity as explored below. Typical frequency bands of FME antennas include: The frequency range of the FME connector means it performs best at frequencies below 2 GHz. Its VSWR is 1.3 and the electrical working voltage is 500 V. Its frequency range is DC to 2000 MHz (2 GHz), and sometimes higher depending on the manufacturer. The FME connector has an impedance of 50 Ohms. FME connectors are available in bulkhead and panel mounted versions and can be obtained with a right-angle orientation. It is this protrusion that gives rise to the nipple connectorname. In the female connector, the insulating material forms a white plastic tip with the receptacle housed within.
The insulator material is made either from PTFE (Teflon) or Delrin plastic.
The body of FME connectors is brass and typically nickel-plated, with a gold plated center pin on the male and a phosphor bronze receptacle on the female. The diameter of the female connector is 0.276 inches (7 millimeters) and the threading has an 8mm (M8) by 0.75 mm pitch. Most FME connectors are rated for at least 500 mating cycles. There carry a hex nut and flats that allow tightening with a wrench. As with most threaded connectors, the male threads are internalized and the female threads are externalized. Its small and compact design also allows cables with this connector to be snaked through small spaces in vehicles, mobile phones, and other portable devices.įME antenna connectors are threaded barrel-shaped connectors that mate by screw-coupling. The FME connector (also known as the nipple connector or SAP connector ) is a miniature connector that has been developed specifically for mobile applications where antennas and cable assemblies may be subject to vibrations and mechanical forces. Antennas are usually terminated with an FME jack (FME female). FME stands for “ For Mobile Equipment”and denotes this radio frequency connector type as being primarily for vehicles and other mobile applications. FME Antennas: Antennas with FME ConnectorsįME antennas are radio antennas that are terminated with an FME connector for connection to antenna cables and other radio frequency equipment.
