I have had the same set up for 9 years and I did the install myself. Never have had any problems at all When the installer comes out I will have the pole set, wires run.
You do know the pole must be a 2"od pole, yes?
Yes I do but I called everywhere and could not find a 2"OD in my area. So I just picked up an 1 7/8 pole at my local fence place. I will either drive a self tapper threw the mount into the pole as others have done or I bought a 12" piece of 1 7/8 ID with a 2"OD and slip it over and weld it on.
