Well, how big is your pole?
The Sadoun page says the 6'er will take a 3" pole.
That's the version with the polar mount.
The other version with the stationary mount, probably won't fit onto a pole at all.
Of course you might fabricate some sort of bracket, but I'm assuming that's not the goal.
And of course, a phone call to Sadoun should confirm any of these comments.
I'm sure he'd be quite pleased to chat with you, especially if you're buying the dish.
edit: server was very sluggish, and Sadoun beat me to the answer. - :up
Yes, I noticed the Satelliguys server was sluggish.
You are right and 3" is the max pole diameter.
Techfizzle, check your pole diameter. If the ID allows a 3" OD pipe to slide in, just slide a 12" long piece 3" tubing half way in, then weld it around the perimeter.
