Garmin wind cups missing

[GentleBreeze]

Has anyone out there had problems keeping Garmin animometer wind cups falling off their GWS-10 units. My new GWS-10 unit was installed December of 2010. I thought that when the original set suddenly came up gone off the top of the mast that maby I failed to align them correctly on installation of the unit. I went up the mast and replaced them in May 2011. Now the May 2011 unit is gone and I have had to order another set.

I called Garmin but they offered no answers as to why it could be happening. They also said there is nothing in their technical database of the problem occuring this often. This will be the third set since December 2010.

We here in Texas have had the hottest summer in many years. Could it be UV and heat damage?

What say you????

Generally birds are responsible for this. If not try to use some glue to the attachments.

Lets try this again. Seems I left some extra characters in my new post!

UV and heat, quite possibly. I've also learned that anytime anything aloft "gets bent" or goes missing, it is often from birds landing on it and breaking if off because it was not designed to be perched on.

Depending on the cost of the cups versus shipping and handling, you might want to order a spare set at the same time.

Only a webcam or wildlife camera is going to confirm or refute a bird problem. But if you can arrange some steel wire (i.e. piano wire) in the form of vertical whips that come up around the wind cups, that might discourage the birds.
