You didn't hear? The reason for the bungee cords is because the Star Gun mount's center screw that holds the thing together apparently stripped out and can't be tighten back down to hold the antenna up anymore...
DJ was driving down the Interstate dragging one of those $220 Coily's behind his van!
Another thing I found out, was the shop that installed the antenna's, and mounts tried to talk DJ out of mounting these antenna's in this manor, but since that's what DJ wanted, they did the work...Moneys, Money...
