will try grab one some time.

Does anyone know if technically you should have planning permission for an anemometer on a pole?

I think anything over 3m needs permission, but thats for radio antennas etc. However I have read that unless a neighbours objects councils dont go around enforcing it. I think one of the main reasons is for safety, so it doesnt come crashing down. ( dont quote me on any of this , just picked up a few things on the www a while ago)

I have increased mine by approx 5 feet, making it about 12-13feet

Its a washing pole in concrete and then a TV pole bolted on. It was wobbling a bit today ( gusting 40mph) but looks solid enough. Just wondered if anyone else had problems with it wobbling or should I say oscillating ? thanks

Paul i found 12ft was around the point that any more than that and it started to wobble / wasn't straight.

if it is straight and fairly sturdy then it will be fine, a bit of wobbling isnt bad anyway i think.

15ft+ and you need guying wires
