You guys may think that I am silly or something but I thought this was a good idea. I created a simple little device to remind me to put my antenna on the jet and remove the overflow plug at the same time before taking off down the runway. It's simple. Simply a smaller tube (to fit over the antenna threads) inside a larger tube (to go over the overflow fitting) with a steel block in between to keep the fuel from getting to your antenna threads. It's obtrusive enough to remind anyone to remove it before flight.
