The hidden antenna thread got me thinking about my stock antenna, it seems like mine gets horrible reception. Has anyone upgraded their stock antenna to another full size antenna? Or better question would be if I upgrade my antenna would I get better reception?

 

Also, I already upgraded to a Pioneer Deh-5100ub head unit which is HD Ready.

 

Ah, well I'm an idiot, guess HD Radio Ready doesn't mean it comes with it. Looks like now I have to buy an HD Radio receiver as well. But while I'm at it any suggestions on stock antenna upgrades?
