The short answer is no, you can't. There's the possibility that it might be used, but I certainly wouldn't count on that. So far, I think your best bet would be to return/exchange that antenna for the right one.
Another possibility is that you can make anything work if you want to bad enough. It would definitely not be easy/cheap, and probably wouldn't work very well.
