Product Description
ARS-G543 - SO-239 UHF Female to Mini-UHF Female Coaxial Adapter
The ARS-G543 is a compact RF coaxial adapter designed to connect equipment and cables using a standard UHF female (SO-239) connection to equipment using a Mini-UHF female connector. It provides a convenient way to adapt between full-size UHF connections commonly used with two-way radios and amateur radio equipment and the smaller Mini-UHF antenna interface often found on Motorola and other mobile two-way radios.
SO-239 is the female UHF connector, while a PL-259 is the corresponding male UHF connector. This adapter provides a female-to-female transition between the standard UHF/SO-239 and Mini-UHF connector systems.
The adapter features a rugged nickel-plated brass body with precision-machined threads and a knurled center section for secure hand tightening. Gold-plated contacts provide reliable electrical conductivity and corrosion resistance for demanding RF applications.
