Mike, the remote antenna on the refurbished 532 I just purchased does the exact same thing. The first time I used it, I couldn't get the remote to work out past about 5 feet, but finally figured out the black rubber part of the antenna had separated from the connector. It works fine now, but doesn't take much for it to work it's way off again. I carry my remote in a belt pouch, with not much risk of putting pressure on the antenna, so it must've been that way when it was shipped.
Anyway, it's no big deal as long as the user is aware of what's happening and pays attention so they don't loose the antenna. Now is a bad time for me to be without the remote because it's prime coyote hunting time, so I'll either solder it myself or send it back when the season is over.
Just something I thought you might like to be aware of for the future.
After thinking about it, is there a possibility of just buying a replacement antenna? Seems that would be an easier solution than sending one back for repair.
By the way, I'm very happy with my "refurbished" Foxpro 532B. The price was great and I used it to call and kill two coyotes on the very first outing. There's a picture in the photo gallery.
Thanks,
