I just got the 2902A station. It seems like a nice instrument, and it gives the readings I expect compared with some other sensors I already have. For the wind speed and direction to make any sense, I think my best option is a roof mount on a decent length pole, given the large trees all around the house. I have a conveniently accessible place to mount near the peak of the roof, and it's there now on little 5' pole but I'm thinking it should be significantly higher. The straightforward way I've seen of mounting masts using standoffs with U-bolts seems intended for permanent install of TV antennas, etc. If I have to clean this thing every three months, I'd prefer something that is easier to take down and put back up. Any ideas out there? Is there such a thing as a tilt-over mounting that goes on a roof?
