Well I finally put up my pole for the slimline install soon to be. All I have left to do is run the coax. Its a 1 7/8od sch 40 pipe with a 1 7/8id with a 2”od sleeve slipped on and welded. The pole sits in a 12” dia hole 44” deep, which took 6 ½ 80lb bags of cement. I think that should hold here steady I also put 2 six inch carriage bolts threw the pipe.
