I'm having a hard time discerning what you are trying to ask.
When you do as dfergie suggests (although I'd say that for a 10' dish, I've mostly seen 3.5" - 4" diameter poles), you normally have something welded near the bottom end of the pipe or a hole drilled through and a large couple of bolts mounted. This is so that the concrete will form around this object protruding from the pole and prevent the pole from spinning around under large wind loads.
Another polar mount scenario include a concrete slab with a square peice of steel laying flat on the surface and bolted to the contrete. This steel piece is either welded to the bottom of the pole, or is fabricated with a sleeve that the dish's pole is slid down into and bolted into.
