Product Description
UHF Female SO-239 to SMA Female RF Coaxial Adapter
The American Radio Supply ARS-G828 is a compact RF coaxial adapter designed to connect equipment with an SMA female jack to coaxial cables or equipment using a UHF female (SO-239) connection. This adapter provides a convenient way to interface different connector standards commonly found in amateur radio, two-way radio, scanner, antenna, and RF test applications.
The UHF Female SO-239 to SMA Female Adapter provides a simple and reliable solution for connecting RF equipment and coaxial components that use different connector standards. Its durable metal construction, knurled grip, and gold-plated center contact make it well suited for amateur radio, two-way radio, scanners, antennas, SDR equipment, RF testing, and general coaxial applications.
UHF connectors are commonly used in amateur and CB radio applications, while SMA connectors are widely used on compact RF equipment and handheld radios. This adapter is intended to provide a convenient mechanical and electrical interface between compatible 50-ohm RF components.
Note: Our black colored connectors are plated with either Black Nickel or Black Zinc Chromate. These electrolytic plating turn the surface black. This plating will provide corrosion resistance and maintain electrical conductivity with essentially no loss. This plating can be found in solar and space applications.

Great Product
Great Product. Connect your handheld to a big antenna!! Works great!!! The pigtails never last long. The wire gets turned and twisted resulting in no connectivity. This works great!!!!

Good " local" supplier
Nice to have a somewhat "local" supplier when you need just one more thing to make it all come together ! Shipping was a little slower than I am accustomed to though, an order placed on Thursday shipped on Monday. - Seller's note: We endeavor to ship all items within 24-72 hours... excluding weekends.
