Default GPS antenna under cowling

For those who have mounted GPS antennas under the cowl, can you share some pics? Did you build a shelf on the firewall? Engine mounts?

Donít know how to do pics but yes, mounted a shelf on the firewall for my GPS antenna for the GDL-82. Works flawlessly. If you send me an email address I can send pics that way

I did it on my -8. I used the F-01201R-1 shelf for the RV-12.

Default Engine Mount Shelf

We made a little shelf attached to the engine mount.

Default GPS antenna

I put both Dynon and Garmin antennas under the cowl. I've got 26 hours flying and both working just fine. You can see it here. Note my shelf is removable.

Here's mine:



Dynon and Garmin antennas mounted side by side. The Dynon antenna is less robust than the Garmin when it's hot under the cowl. It takes a few minutes to cool it off after a restart. The Garmin, so far, has been rock solid.

In case anyone cares, I will not to mount any IFR navigator GPS antenna under the cowl, bad environment for a critical device.
Personally I'll take function over looks any day of the week, but that's just me.

Hey Walt, I care. And I will agree with you. A delicate electronic device should not live in a hot dirty environment.

GPS antenna's under the glass cowl have been working great for many proven years. If your cowl was painted with a highly metallic paint (fine aluminum powder), it might effect performance??
