With my current antenna configuration, I am able to receive all the major network digital channels except CBS. This is the furthest away transmitter (70 miles). Currently, with the antenna located at 31’ above ground level, the TVFool analysis chart states NM of -4.2. I found that I can sometimes get CBS and sometimes not. It’s intermittent.
The question: Should I go through the effort of adding another 10 ft. to the antenna? Based on the TVFool analysis, it would lower the NM to -1.9.
Will it ensure a much better reception to CBS? This is more of a logistics issue for me than cost. Because of the height, I’ll have to add guide wires for stability and hope to put it up on my roof without killing myself.
