Roof or Wall installation?

[daveyard]

New guy here.
I need to get this 90cm dish on my roof or close to the top of the wall.
Any tips or insight on mounting?
Thx!

What type of wall material?

I would go yard post/pipe mount or then chimney or then roof or then wall especially if it were brick; if its wood OK but just not on the soffit/facia area.
