Absolutely nothing wrong with that location either. Fitted to my -6A, I have an Archer VOR antenna in one wingtip (barely seen above power pack in upper photo) and marker beacon in the other wingtip. Neither seems effected by the Whelen components and I routinely operate with the strobes on.I would like to add a follow up question. My strobe system has 2 boxes. I'm thinking of mounting a box in each wing tip where the strobes are. Does anybody see anything wrong with that location? Thanks Lyle
