The signal strengths at 17 feet (your first posting) are in the -3.0's thats bad. The signal strengths at 75 feet and 125 feet are are from 13 to 9 NM(dB). You can go to the >START Maps< part of tvfool and put in antenna heights of 17 to 50 feet and find a height that gives signal strengths of about 12 to 10 NM(dB) or a little better and put the HD7698P antenna and AP8700 preamp at that height. Do not use the distribution amplifier.
Thank you very much! If the distribution amplifier is not a good idea, what would be the proper way of splitting the output from the antenna? And, what should the antenna be mounted to to attain such high heights? Should it just be a really long pole on our roof? Thanks again!
