Windy Ridge

[Roadster99]

Greetings to you all.

I intend placing a motorised 85cm steel dish on a 2" galvanised steel pole mounted on two strong wall brackets. They will be mounted on a north wall facing over the roof ridge. The west aspect will be slightly sheltered from the prevailing winds by the L shaped roof. All other aspects will be open to all the elements. My question is:- would it be better to park the dish side on to the wind or with the dish back to the wind?

At first thought and I note from some other members that maybe side on would be best but that would leave the LNB exposed to side winds and also the dish could put side load on the DiSEq motor. Having the dish back to the wind would protect the LNB and its arm and maybe not put as much strain on the motor.

The thoughts, observations and practical experience of the forum would be appreciated.

For the least movement of the dish, then side on is best, there is minimal surface area on the LNB and boom arm compared to the dish surface. Having said all of that, I never bother to move mine and it is still up there.

just do it and see. If you go to the members systems thread you can see mine. Apparently it is very exposed (according to one distinguished moderator) but it still works ok with a 1.2 m dish. I mean, let the bas**d put a bit of effort in moving the dish, it's a motor, isn't it?!
