Hi Martyn, since my post I had to pull it down again due to a dodgy connector, so whilst it was down I added 2 cable ties to the vane, put it all back up agai, low and. Behold the little bas… Came and perched on the blooming dogleg, that’s only a problem if it stopped the vane, i can’t really cable tie that cause it may interfere with the solar and uv
