Exclusively from Signal Stuff! There are a lot of SMA-F to SMA-F adapters out there to let you use an SMA-M antenna on a radio wanting SMA-F, this is the other direction. We used to put a plastic sheath on them, but now we have them custom manufactured just for this purpose so it’s sleek, clean, and simple!
While the need for this may not come up all the time, this is a great adapter to have in your kit to ensure all the antennas can attach to any of the radios =]
Though it is black this is 100% made of metal, not cheap plastic — it just looks nicer with a low resistance conductive black coating.
