Tucson Satallite Radio Antenna
 

Hello everyone,
I have a 2009 Tucson and haven't had any problems with it since I bought it new. I am disappointed by two things though. The first is nothing I can do anything about, and that is the less than desirable power from the 4 cyclinder, but I knew that when I bought it.
The other concern is on trips to Maine I get sporatic radio reception when going through valleys. I went to the dealer to try and buy a bigger/longer/better antenna, but they don't have anything but original equipment.
I went to Best Buy and Radio Shack and they didn't have anything for my car either.
Does anyone here know about a better antenna that wll be a direct screw in replacement antenna (I don't want to drill any holes, or have a cable hanging out the window to a mirror, or bumper mounted, antenna) ?
Thanks for your input.

UPDATE:

Still no luck with a replacement antenna, and I thought I would add here that it was suggested to me that the problem may not be the antenna, but it just might be the receiver.
