After seeing how it fits together, I think I like the commercial configuration of the antenna connectors better. It appears to be physically more solid. That is certainly the case when using the BNC adapter with the Wouxun. On a different subject, The Wouxun speaker/microphone configuration is the same as that of the Kenwood THF6. So, if you already own a speaker/microphone that works with the THF6 or other compatible Kenwood units, you are in business with the Wouxun. I didn't know that when I ordered a speaker/microphone for my Wouxun. Mike Duke, K5XU American Council of Blind Radio Amateurs
