Re: BBQ Dish Sanity - more info



Hi All, for what it is worth I must agree with Rick as I have one of the
1.8m dishes that he is selling and last night we had the beginning of our
windy season and it was that bad that I fully expected to loose roof tiles.

The dish wasn't parked like I had to do with the solid 1.2m dish that I used
before and was fine when checked this AM and when standing on a large ladder
in front of it I can feel the wind coming through the mesh with only minimal
movement of the dish.

If I had left the previous dish in the same position it would have ruined
the rotators (kr5400) and itself.

Regards Reg Wood VK2RW
