Seems like it'd work....
I tried using a couple of them as belt hangers (the plastic thing broke within hours, but the replacements seem to be solid enough), with poor results, but a mic clip in the car seemed to work adequately.
(I don't consider this a formal test - the clip is mounted for a small mic, and the radio barely fits down there.)
If you can find one (try a CB shop, I guess), for a couple bucks, it's probably worth a try. Why the heck they didn't use a more standard belt clip, I don't know. I've gotten used to the thing, but I still don't trust it. (I wear the thing a good part of the day when not in a chair - I'm too wide to leave it on
.) Radio Shack has 'em, too, but I'm not sure if they were "in store" or just on the web the last time I looked.
