Without a TV Fool report I can only presume your situation is average with many of the stations operating in the UHF frequency range. The wave lengths in the UHF band are short enough that a few inches of wire can act as an antenna element. At 25 miles, the amount of power available is still substantial, enough to overcome the inefficiency of a poorly tuned antenna element. So, no shock or surprise. I've use an unbent paper clip as a UHF antenna... just to demonstrate the idea.

One other possible explanation to consider though, a bad connection between the coax shield and connector shell can cause the entire length of coax to behave like a long wire antenna. If you're having a hard time with reception, give close scrutiny to the connectors, they need to be secure physically and electrically.
