2" aluminum poles are hard to find, around here anyways. So here is what I did...... 6 Foot Schedule80 2" PVC pipe sunk 30 inches in the ground with concrete. 2" to 1.25 adapter on top with an added 1.25 inch coupler (Make sure you get the coupler flush with the adapter. The slimline backing fits nicely on the coupler. Peak dish and tightened it down. I haven't had any problems with it what so ever and spent 5 bucks........Comments anyone?
