Paul, A few years ago, Don (W3LR) bought a mile of aluminum electric fence wire to use as radials for a 40/80 vertical for Field Day. We only used it two years. I still have it in my barn. Not sure of the gauge, but you are welcome to a length of it. I'm in rural Coopersburg (PA). It may not be exactly 16ga, but very close as I recall. 73 de The Grump
