I have a large kayak the boat rests on the antenna when I get it on the roof rack. If I move it to one side, it rests against the side. Im trying to figure out a way to protect it with foam. But this isn't ideal. The J carrier may help, but my boat is big and heavy and I don't think I will be able to load it by myself. Anyone have the same problem? Is there a way to mount another rack system that gives more height to the rack so it isnt so close to the top of the car or antenna? Any tips or advice? Anothwr solution all together? Attached are pics of my issue.
