I think I found a winner...well as with the long-range antennas for TV reception, how far do they go?
according to this ebay item, you can receive up to 980 miles
Super HD TV HD Antenna HDTV FREE Digital Channels 980 Miles 13ft Cable UHF/VHF | eBay
It will also receive Fox News in 1080p HD 4K all at the same time
all that for $6.98 and free shipping. (If you order in the next 20 minutes, maybe you can even get a second one for an additional fee of $400?)
Personally, if it can't receive Martian TV in 16K, I don't want it.
It's too bad the station I wanted to receive is 981 miles away...
Seriously, I understand that advertising usually stretches the truth a bit, whether it's by a politician or the gas mileage of a car, but isn't there any law that can hold this type of seller accountable for such over-the-top claims?
What if Chevy was advertising a pick-up truck saying that it gets 500 mpg with a disclaimer that "actual mileage may vary, check EPA website", would that fly?
Not only are such sellers fleecing buyers who don't know better, but they are also progressively putting real antenna manufacturers out of business and giving OTA a bad name.
Now, to answer your question, I think that measuring an antenna by range is an gross oversimplification. It will of course depend on the terrain and the height of the antenna and will be limited by the curvature of the earth, but it also depends greatly on the radiated power and the beam pattern of the transmitter...
