Using the Stock XM Antenna for Sirius

Hey Gang,

Got another question, I will be replacing my stock headunit for many reasons but right now I'd like to use the XM antenna thats painted and on my roof for Sirius service. Is that possible or is the antenna made in such a way that it won't pick up Sirius?

Thanks!

not possible at all...but if you wait till fall/winter you just might be able to since Sirius (awsome) is merging with XM (sucks)
