Does anybody have any ideas on making a simple mount for the Windy Nation PMA, preferably using steel or aluminum? I built a basic wood mount using a weather treated plank/tail with a 1.5" plumbing nipple to attach to a 5" pipe (that fits over the longer 1" pipe). The PMA itself is securely strapped to the plank. It works for now, but it isn't as responsive as I'd like when it orients to the wind and I'd like to get away from wood and use something that will last longer. I'm interested what some of you have come up with?
