......... Broad Cast Signal .....
I may not being using correct terms or terminology last time I used a on air antenna was over 60 years ago.. When a station broadcast a signal is that signal coming off the tower flat like a disc or shaped like a umbrella. The reason I ask this question is my location 1998 feet + 20' in elevation and 65 miles west of Knoxville TN. Line of sight east has 2 mountains ranges 200--300 feet higher in elevation than my location ( 38571 ). Knoxville TN is appromatley 800-900 feet lower in elevation. I have read numerous articles claiming the height of the transmission towers at Sharps Ridge in Knoxville I have yet to find real figures. If any one knows these figures please post them and any other information regarding signal strength on this subject.

All of that data is in the FCC licensing database. http://www.fcc.gov/encyclopedia/tv-q...station-search
Some of the data is in formats that are a bit obtuse and require some training to decipher into understandable descriptions and data. Quote:
The tower sites on Sharp Ridge are at around 1300' ASL elevation and the towers themselves are up to 1500' tall above that site placing the transmitting antennas around 2500-2800' ASL, depending on the location on the tower. Please note that the TVFool calculations do not take the vertical elevation profile of the transmitting antenna into account as this data is often not in the FCC database. |
