RF coaxial connector
MCX Coaxial Connectors

Manufacturers direct radio frequency coaxial connectors McXj-1.5 MCX straight cable head pressing RG174 316 line (MCX-C-J1.5-4)

MCX connextors use a snap-on interface and usually have a 50 Ω impedance (some are 75 Ω) .

They offer broadband capability from DC to 6 GHz.

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.
