The antenna has a proper SMA mount but the beofeng has a plastic rim that sticks up about 1/8 inch. It uses a standard antenna to ensure full contact. The base of the antenna is too wide to fit inside. As a result, there is a chance that she will make proper contact. This can also explain the alternation between good and bad answers. Full Disclosure: I'm using the Beofeng RTP version, but I believe all 5 series are the same form factor. Just to confirm, doesn't work for me.
