Well it was right for me.....I'm from Kansas, so pretty much the terrain and trees aren't much of a factor where I live, so that's why I pay attention to the miles on the box, but you're right....it would depend on where you live. I realize there are a lot of other factors involved as well.....My family and I used to do various broadcasts, experimenting with different antennas and transmitters, so I definitely know what you're talking about. I was just trying to give this person a simple option.
