Product Description
Amphenol SO-239 / SO239 ( 83-1R ) RF/Coaxial, UHF Straight Flanged / Bulkhead Jack (f), Solder
Ours say SO-239 on them
Used, but working - they may still have wire soldered on from previous application. Just desolder the wire, and you'll be all set. They are high quality silver plated so they have some tarnish on them.
