If you saw some of the trees that I have around, you would understand that it is impossible to get above them. It is very difficult to site the instrument, there is no question of that, but when you live with houses and trees you do the best you can. Sometimes you have to improvise, and that is what I did and it has helped me, now whether it will work for everyone is doubtful. When you have swirling winds, and an ultra sensitive vain, you are really in for a challenge, and adding some weight to the vane will help to settle it down some. It is very loose and light.
