Go to home depot, or even better a local fencing supplier, get a 8 to10 feet length of the thickest wall 2.75" or 3" pipe you can get, a post hole digger, and a sack of quickcrete. Dig hole, mix concrete, put pipe in hole, put concrete in hole, level and brace pipe, drink beer, the end.
Wait three days, mount dish, call me to come inspect it.
Now what was so hard about that?
