I have verified the accuracy of the first plot by using the interactive tool. The antenna height and location are correct. I cannot see what is between my location and Holston Mtn, but my line of sight appears clear, so something else must be going on. Because I am in the beginning stages of installation, I have yet to ground the new RG6 cable to a grounding block. Also, the new RG-6 passes within 6" of the house's electric service feed. Could either cause the pixilation? Thanks..RJR
