I'm experiencing some "wagging" on my VOR / LOC indication (GTN650Xi + AFS4500) an trying to track down potential causes.
My Archer Nav antenna is installed in the left wingtip using the same strategy others have shown here -- as far aft as practical, away from the tip lights. I do have foam ribs inside the wingtip, though. Will this cause a problem with reception? I presumed not when I intalled it, since the instructions say it can be laminated into a fiberglass structure.
Tonight I was able to pick up a VOR at ~30nm, 1700AGL, but the indication wags +/- 4 degrees on a 6-10sec period. AP is unusable to track the radial due to the swinging.
Wouldn't be as concerned, but I'm planning to start IFR training and would like things to work properly for that endeavor.
I could cut away the foam ribs. Also remount directly to the tip rib on a piece of angle, to bypass the hinge connection (the hinge did have the anodize sanded off where the antenna is riveted on).
