Has anyone tried mounting there GPS antennas along with XM weather antennas on the firewall like Van has it done on the -12?

I would be interested in pictures of instaltions and any noted problems with satellite reception.
 
It's been done

Have seen several successful installations putting the Garmin 430 "teardrop" antenna under the cowling. When I asked some of the guys at SteinAir about the heat affecting the antenna, they said it would not be an issue.

Some I've seen have been mounted to a bracket attached to the firewall, and some have been attached via U-bolts or Adel clamps to the engine mount. Just make sure you have it high enough so that the firewall can't obstruct the signal.

Not sure about the XM antenna, but someone else may chime in.
 
We had both antennae under the cowl...

...on my buddy's -4. It was also painted silver but it received very well.

Best,
