I know this subject has been talked to death somewhat, but who is using their GPS for IFR approaches including vertical guidance, and where have you located your antenna?
I'm getting ready to install a Garmin GTN 635, and I intend to use it IFR in my RV-7. Currently, I'm vacillating between just aft of the canopy, on the fuselage just aft of the firewall in front of the windshield, on the glare shield, and under the engine cowl just forward of the firewall.
I'm leaning towards either on the fuselage just aft of the firewall or just aft of the canopy to get the best view skyward. Heat and the dirty RF environment are a concern for under the cowl. On the glare shield works fine for my 795 handheld antenna, but WAAS is another thing.
I'd appreciate any thoughts on the subject from people with successful WAAS approach capable installations.
Thanks in advance!
