I traded in my H3 for an H2 and I really like it so much better.

However, the radio reception isn't all that great like the H3's.

I have looked at antennas but nothing seems much different from the factory antenna.

Anybody done anything to improve it?

 

Are you talking about satelite? When I bought my 05 new, the reception was great. I could go beneath underpasses, tunnels and never lost signal. But about a year or so ago, that changed. If I just go under a tree canopy I lose it. I think something changed with the XM satelite configuration.
