While I've installed hundreds of F12 antenna rivets, I haven't encountered any longterm (or short-term) problems with them loosening up. I wonder if putting rivets on the opposite side as redundant fastening would help. Maybe putting a little opposition tension on them would help - this is a theory. Another thing you could do is to put in a TEK screw to backup the rivets. (A TEK screw is a chisel-tip, self-tapping sheet metal screw. Get the ones with Phillips heads and they install in a couple of seconds with yoiur cordless drill. I haven't seen one of those come loose.) Use of the TEK screw to me is a faster and better method than using a hacksaw to cut the ends of the elements and then using hose clamps in the traditional method (a LOT of retro work!). As far as replacing them, it couldn't be easier. Use your cordless drill with a 1/8" bit and they drill out in a couple of seconds. Maybe we'll hear from Tom, N6BT, on this topic. Maybe not.
