This series of pictures just shows the assembled antenna up on the roof.
The first picture shows one of many ways it can be done. I have an unused chimney that is large and strong. I chose a chimney strap system. It consists of two corner brackets and stainless straps that go around the chimney. Turnbuckle type bolts let you tighten it. The mount is strong. You can also get roof mounts in various configurations. One of the best and least invasive are the brackets that mount on the side of a house at the peak. No holes in the roof and you can screw into solid wood.
The second picture shows one half of the array and how the matching transformer is connected. I attached the leads with stainless steel machine screws with washers on both sides and a nut. Then ran the bolt through the white plastic to brace and bolted the connection to it.
The third picture is of the splitter being used as a combiner. A coax from each elements matching transformer is connected here so they antennas can be 'combined' into one cable. This splitter actually degrades a bit of the signal but the second element will bring in enough extra signal to make it worthwhile.
The fourth picture: Bolted to the mast pipe is the coax grounding lug. The short length of coax from the splitter is on one side and the other side is the coax to the TV. The ground wire is connected to the lower pipe and goes to a ground rod. There is a grounding screw on the grounding lug that the ground wire can be attached to. My wire is attached to the mast below the rotor.
Here you also see my channel master rotor. Where I am the signals are within a 20 degree arc with some of them being 180 degrees to the rear.
The fifth picture shows the entire antenna from the front.
