Today I happened to pull into a parking garage and unscrewed the coil / whip assembly. I immediately noticed that the coax connector on the magnet base was filled with water. I had heard of this happening on a 1k so I was on the look out for it. I noticed that there were three large cracks in the top as if I had hit something with the antenna. I don't remember hitting anything at speed but maybe I did. I am thinking that I can drill a hole in the bottom to let the water out and seal up the top. Has anyone had to do this on a 5k and if so is there anything to look out for?
