Basically the report shows the stations are very weak to receive. Generally the 3 important columns I look at are NM(db), miles, and path.
NM is basically the strength. Anything in green or yellow is receivable. Once you get into the red area where the NM is just above 0, reception does become more difficult. In the purple area, it becomes almost impossible. On your report, NBC and FOX are way down at the bottom.
Dist miles is how far away you are from the transmitters. In your case you are about 60 miles away and the towers are to the NW of you , indicated by the 321 Deg compass reading.
The path is how the signal gets to you. If you have no hills or obstructions in the way, and you are fairly close to the tower like PBS, then you have Line of Sight, or LOS. If you have a mountain/hill or 2 in the way in your way, your signals must bend around it either once or twice, this is called 1 Edge, or 2 edge. Tropo is basically saying you can only get a signal during certain atmospheric conditions.
Do your have neighbors around you that have an antenna that you can ask how there reception is?
I would re-run the tvfool report, but this time plug in the antenna height at lets say 25 feet. Height of the antenna is a major factor in receiving channels.
If you did want to attempt this, you will need a BIG Vhf/Uhf antenna mounted outside with an amp. Buy stuff at like Radio Shack so if it did not work, you can always return it easily.
