Perfect Adapter
This adapter fit perfectly into my HT Baofeng. I had previously purchased an adapter from China, but the SO-239 side thread did not fit the male connector well. This adapter was perfect. I recommend.

Worked Prefect!
So I buy two Baofeng radio's with the thought of hooking them up to an outside antenna. The radios have a SMA connector like I had never seen before. I get on the internet hunting for something but not knowing what. I call American Radio Supply. The guy knew just what I needed and I have two friends with these radios so I ordered five. I thought it was too easy, but when they came they worked perfect. It is great when you have people and parts that are better than what you hope for.

Just what I needed!
I carry the UV-5R up to the shop with me, there I use this adapter to hook it up to an old magmount antenna on a metal shelf unit. The set up works great and I can unhook it to go back to the house for coffee. Good stuff.
