I'm in the process of making a doubler for my GA35 which I plan to mount on the top of the aft fuselage. My question has to do with the actual mounting method for the attachment of the mounting screws. I had planned to use floating platenuts as I have seen other use and in fact Stein sells a doubler kit with this type of platenut. When I went to read the mounting instructions (yes this time I did) it calls out use of a simple flat washer and locking nut for the mounting screws. This is unlike the GA57X doubler instructions which describe the use of floating platenuts as a mounting option. So, is the use of platenuts considered non-compliance with the installation instructions. BTW this antenna is for my GTN650xi. I realize as experimental builders we can probably do whatever we want but I was more curious on a technicality basis.
