90 Prelude Si 2.05 with "stuck-up" antenna

My power antenna is stuck up and won't move when plugged in. The problem is someone broke it off a little and now my reception is terrable so I need to fix it. Does anyone know how? I found replacement antenna's on ebay for $29 are they ok to use? Just wondering. Mine keeps hitting my spoiler and it is scratching it all up when I flip up the trunk cause I forget about it. If anyone has advise on this that would be great. I hate to buy one off ebay unless I know someone has and they worked ok.

you could probalby just break it off, and then make an internal wire on the inside of the trunk or something.

I had the same problem with my prelude, i ended up having to buy a new
antenna.
