I'm sure it's been done so I apologize if it's been done before. For those of you who built the windsurfer you know how the foil can be a pain in the butt. Went to the hardware store and bought copper sheeting. I was able to get about 4000 plus in range in an urban area. I live 12 Miles north of NYC so lots of homes with disruptions in signal. Gonna field test it this weekend pending weather but I'll keep you up todate on an open field.
