PL259SO239

PL259SO239 refers to a specific type of coaxial radio frequency connector. It is a variation of the widely used PL-259 connector, often employed in amateur radio and other radio communication applications. The "SO" prefix typically indicates that the connector is designed for use with a specific type of coaxial cable, such as the RG-8 or RG-213 series. The "239" designation is part of the military or industrial nomenclature for this particular connector configuration.

The PL-259 connector itself is a two-piece, screw-on connector designed for termination of 50-ohm coaxial cables. It is known for its robustness and relative ease of installation, though achieving a perfect seal and impedance match can require careful assembly. The SO-239 is the mating chassis-mount receptacle for the PL-259 plug. When a PL-259 is connected to an SO-239, it creates a secure and mechanically strong connection.

The "PL259SO239" designation, while not a formal standard name, commonly denotes a PL-259 plug specifically manufactured or intended for use with the SO-239 chassis connector, often implying compatibility with certain cable types. These connectors are popular due to their cost-effectiveness and widespread availability. However, for demanding applications requiring high precision or exceptional performance at very high frequencies, other connector types like N-type or BNC might be preferred.
