Antenna question

[Tall Dog]

I have my home theatre setup in my finished basement and sometimes the radio reception isn't that good with the little wire antenna that came with the receiver.

I have an antenna on top of a 30' tower that I use to pick up my local channels in hi-def.

Can I run a splitter off of my antenna cable and hook it to the antenna connection on the back of the receiver to get better radio reception instead of using the little wire antenna that came with the receiver? Just wondering if the tv antenna will work to improve radio reception also, or if I need a different type of antenna for the radio?

Thanks
