Guys which is stronger a 2" .250 wall 6061 aluminum mast pipe or a 2" .125 wall with a 1.75 with a 1.25 wall sleeved inside it.
I can imagine myself with an 8 foot piece of 1/4 inch thick 2 inch diameter aluminum pipe. Stick it between two boulders and pull on the end with my 6'2" 250 pound self. I don't think I can bend it.I forgot to put that in there bout 8 feet long heavy antenna going on it 142 lbs
I assumed the 2 pieces were steel. Go with the 1 piece. BTW 2 1/2 x 3/16 would be stronger yet.Between the two I would go with the aluminum.
