Hi Graham, G3VZV

Pointing straight up with the main supporting boom in direction of the
dominant wind is the best because the dish will offer the minimum surface
to the wind while both yagi's are aligned in a way to be seen by the wind as
about a single antenna.

The above is my experience with less damages into the windy gulf of Naples
