FME Male - MCX Male Antenna Adaptor (CF.22)

FME Male to MCX Male Modem Antenna Adaptor

The Co-Star CF.22 antenna adaptor is a quick and easy way to convert an antenna terminated with FME female to MCX male.

MCX (micro coaxial) connectors are coaxial RF connectors developed in the 1980s. They have the same inner contact and insulator dimensions as the SMB connector but are 30% smaller. MCX is standardized in European CECC 22220.[1]

They use a snap-on interface and usually have a 50 Ω impedance (occasionally 75 Ω also) . They offer broadband capability from DC to 6 GHz.[2] The contact surfaces are gold-plated.

This type of connector is used on the Apple Airport Extreme Base Station's external antenna port and requires an adapter for most antennas. MCX and the smaller MMCX connector are frequently used to connect external antennas to GPS receivers. They are also common on USB DVB-T tuners for computers and laptops, to connect an external antenna to the tuner.

The outer diameter of the plug is approx 3.6 mm or 0.140 inch.

The GPS port on the Teltonika FM1100 uses an MCX connector this adaptor will convert an antenna with an FME female to MCX male which is the correct type for the GPS port.
