I hate to bore people with this story one more time, but it sounds like Slotzero got his answer, and this post brought back memories. Back in the mid 80s, a mail order catalog had a sale on big 10' sat dishes. A co-worker of mine ordered one, and when I saw what he had ordered, I ordered one too. His came first, and he started to install it. The directions said to use 3" ( 3 1/2" OD) "Schedule 40 pipe". He went to the local hardware store, and they gave him Schedule 40 plastic pipe. He questioned this, but they said that was what Schedule 40 was. He dug a hole and sunk the pipe in concrete, and a bunch of us went over to put the dish on it. Once the dish was up there, that pole bent like a fly rod with a 5 pound smallmouth on the line. We tried to tie guy wires to stabilize it, but he had sandy soil, and the dish kept pulling out the anchors. Finally, he called a real pipe company and found that there WAS a steel version of Schedule 40. It came in like 22' lengths, so we cut a length in half and I got half for my dish. But that was really funny seeing that big dish swaying this way and that.
For these little 3' dishes though, it probably doesn't matter what you use. I used galvanized pipe too. I can't remember if it was schedule 40, but it might have been. Not sure if I would bring the concrete above ground level though. I did this on a deck once, and then needed to move the deck, and I couldn't get the darn footers out of the ground, and was cutting grass around chunks of concrete for years. I about pulled the frame off my 4x4 trying to pull the concrete out, but it wouldn't budge.
