Mike,
I would also like to use the Revolution antenna as a dummy "probe" but my layout won't allow this. My receiver is mounted to a Smart-Fly Powerexpander and is to large to place in the nose. The Rev antenna says to cut the receiver antenna 4" long before attaching but I would have to leave it 10". I have not tried this length but am pretty sure it will have a negative effect on range.

Thanks to everyone that posted advice here. I plan on mounting the Rev antenna in the front of the Hawk attached to the bottom of the fuse with goop. This will get a clear shot for the signal and away from CF, batteries, ECU and fuel pump. But I sure would like to mount it out the nose as the "pitot probe". I scaled the length of the Revolution antenna to the length of the real probe and it is within a 1/4" of correct length. Darn!
