I know which way North is. Luckily the wall that the mast is on is pretty much spot on N-S which makes mounting anemometers really easy. I’ve got an anemometer transmitter, but I’ll mount it where I can get to it rather than up the pole.
Freezing rain isn’t an issue in this area so I don’t intend adding any type of protection for it. I’ve had anemometers up on this and my previous house for about 5 years now and I’ve not had a problem so far.
