It appears the entire assembly at the end of the arm has been rotated approximately 90 degrees. We had a bad thunderstorm with tornado warning sirens a few days back and it seemed odd that I was getting single digit wind speeds. I doubt the wind did this and I'm wondering if a hawk tried to land on the top of the anemometer, as it's on 6' metal pole attached to a 10' wooden pole. I've seen a hawk perch next to it before on the arm.
In looking at the manual it looks like that end piece with the sensor in it (cones attach to one end and the wind director attaches to the other end) has no set screw. Has it likely been broken and I have to replace?
Trying to find out so I can order a replacement before going to the effort of taking it down. I'd actually had somebody else mount the entire 6' pole up there for me, so I'm not looking forward to trying to get it down. It's in the middle of a field.
