Soldering a broken Rx antenna OK?

[Finnster]

I sawed my Fasst RX antenna in half after a backflip and lid slide on pavement, chewing all the way thru the antenna tube. The RX works well enough, but the range is only ~75yds. Would soldering the broken end back on mostly cure the problem? I could send it in of repair, but I really can't spare it now, and hate to be out the cash.

Any experiences with this?
