Hey folks,
Simple little question here. I'm going to mount my transponder antenna today and noticed that, like in this picture, there's a rubber gasket that will fit between the antenna and the skin of the airplane when installed:
Do I need to remove this to get a solid connection between the antenna and the skin for a grounding plane? Or is the idea that the lock washer and nut against the doubler INSIDE the plane provide enough contact for the grounding plane?
My intuition's failing me here. Thanks all!
