Furthest reception from your tuner and how?

I know it's all relative, but I'm looking for someone to answer my question about earth coverage distances and gain sensitivity. Does anyone know the formula for FM/Earth coverage based on parallax, and antenna height? Or where I might find it? In terms of absolute distances?

Arrrrggggggghhhh... obviously someone who missed my post in "the best tuner" thread...

I don't remember the formulas for this stuff but as an ex-chief engineer at a radio and TV station I can tell you that if you are more than 60 or 70 miles you aren't going to pull in much. With a high gain antenna up on your roof you'll be be lucky to recv station 80 to 90 miles. As stated above, FM is transmitted "line of sight" and the curvature of the earth is the limiting factor. While some tuners are more sensitive than others, it won't help at the distance you seem to be talking about. Sorry.

Bio....Not sure about your response there, don't ask for help, then argue with people who try and give it .
If you check the website I mentioned not only will you find info about tuners, but several links about antennas and FM reception.
There is also an FM tuner group, which if you went there you would surely find your answers. This makes a lot more sense than going round and round on this forum.
Arrrrggggggghhhh!!!!!!!!!!!!!
