All the Channel Master and Prodelin manuals have a section on making a suitable concreted-in pole for mounting the dish on.
(Interestingly - the text and diagrams are almost identical, to the degree that one would think it's the same guy writing for both companies!)
But that all state that the pole that is concreted in needs to be filled completely with concrete.
I assume this is an easy way of keeping moisture out of the pole, now that the cement mixer is out anyway.
(It probably also adds...
Filling the pole/tube/mast with concrete?
