Hello=20 Nicolas,

With a higher diameter you get more L at less turns, so= more=20 volts per turn. This makes it necessary to use a better wire insulation= or a=20 higher wire spacing, depending on the power. Keeping the coil dry is=20 important, no matter what wire you use. Thus i have to go immediately QR= T on=20 VLF when it starts to rain. On LF, it is enough just to cover the coil= by a=20 trash bag...
