Mini-UHF connectors are a good choice if weight, size and price are important. They are a smaller version of the UHF plug, however they have improved electrical properties, they have a fixed wave resistance of 50 Ohms and they can be used for frequencies up to 2.5 GHz. The compact form is particularly useful for mobile transmitters. Dovetailing on the screw lock means it is securely held, for connections in vehicles, for example. Mini-UHF connectors are also used in computers, networks, antennas and cable modems.
