Has anyone fitted an alterative aerial , we have a  05 wagon, and every time you put the heated screen out the radio reception is crap, plus thinking of  a replacement sat nav stereo so a better aerial is a must, any suggestions would be helpful 

I had shocking signal aswell...

Not affected when the heated screen is on though..

 

But my signal booster is on the c pillar and a wire had been cut by the looks of it I soldered a meter or so onto the wire that looked like it had been cut and now I can get radio 1 and a few others at least but I would like to know where this wire original went to instead of me jus resting it up in the head lining 

The wire my finer is in was the one that was cut with now a solder wire on it..

 

And to your post about poor signal when the heated screen is on a quick search on Google shows its down broken heated *lines* the ones that run across the glass.. 

 

Sorry for hijacking 

Cheers I will check the heating elements
