The results of available channels and Prime Time programming in your area is an estimate based on the location details entered and the location of the TV transmitters in that area ( < 35 miles; 35-50 miles; and 50-60 miles), and is not guaranteed.
The estimated signal strength shown in this chart is calculated using multiple factors, including an antenna height of (25), distance from broadcast towers transmitter power, terrain obstructions, curvature of the Earth, and other factors that affect signal availability. Your specific location will be unique in terms of local terrain, foliage, and installation details which will affect your reception.
These results should be used to estimate what channels you might expect to receive based upon the location details with an antenna placed at a height of approximately 25. Most installations will require some optimization in terms of antenna type, quality, and placement.
