2 foot square if large. Please advise the details of what material you =
used and how you mounted it and how you connected it to the GPS antenna.

Fred,
The AV100 installation manual suggests the use of a ground plane. We =
installed the factory unit without a ground plane - test operated the =
system with the aircraft parked - and everything appeared to be okay. =
When we flew the aircraft however, the receiver had a difficult (almost =
impossible) time staying locked onto the satellite. I spoke with our =
tech rep at WSI - who said that "truth be told ...the satellite =
broadcasting the WSI data is very low power ... which makes it important =
that we give the antenna every advantage possible to do it's job" ... =
meaning, it would be best if the antenna had a ground plane. At Wayne =
and Paul's suggestion I installed a 2 square foot ground plane "shelf" =
that is suspended under the canard hatch cover - and it made a big =
improvement. The WSI signal reception is (now) strong in flight.

Hi Bob,
The guys have installed the WSI receiver in the new XL demo plane
and are having reception problems. You have had good luck with the
system and I am curious as to how & where you mounted the antenna.
My take is to mount it to a large ground plane above the machinery
atop the canard. This should give us about 2.5 square feet of =
plane
and hopefully fix the problem, the ground plane they have now is
about 4" x 12" on top of the canard and amongst the servo =
motors...
What are you feelings/comments?
Many Thanks & Fly Safe,
Wayne Lanza
P.S. Do you know any of these guys?
