Has anyone tried using one of the small rooftop towers on a metal roof? I am about to reroof my house. Right now I have both a vertical and a dipole attached to a piece of pipe attached to a chimney. I intend to do away with both chimneys when I reroof and I want to use metal roofing so I need another way to put up everything. I thought about putting everything on a pole in the yard but I fear I will come home to find kids trying to climb it.
