Well, what I am going to do is buy an 8 ft. 4x4 wooden post and bury it into the ground 3 ft. without concrete. Then I will buy two 5' antenna masts that simply snap together and use clamps and such to attach them to the wooden post. This will make the overall height about 12'. And if I have to clean the anemometer, I can just take off one of the 5' antenna masts, which will then make it about 7' tall.
