Bill and I might use different methods. I am not in a position to ask Bill what he does (other than fit well installed aerials and all the other stuff invloved in doing that).
Bill knows that I use his local competitor for my aerial installs.
I am not going to say what I do, and I am sure Bill will say the samething.
I am sure that Bill will agree that there is no perfect solution.
You win some, you lose some and sometimes you get even.
