Shown is my roof mounted mini antenna farm. The roof mount hardware is leftover from the previous home owner's satellite dish. I built the mast out of scrap steel pipe. The cable run goes through the roof where an old chimney used to be and drops right to the basement computer rack.
Scanner antenna (on left mast) is a $29 Radio Shack special. Center mast is a 2-meter amateur band antenna. Spot on the right is reserved for fuuture use. Cabling is all RG-8 low loss.
