I've set them up, and re-adjusted them to increase service. The fact remains that you are depending on weather and nature for television reception. I have an uncle in upstate NY that loses it during heavy snows in the winter. I have other friends in the south that loses it during heavy rainstorms. If you live in the woods, and things like trees or power lines are in the way, they can create interference.

I personally sold my TV years ago, bought a projector and high quality glass-beaded pull-down screen, hooked it up to surround sound, and got a Netflix account. I just got tired of relying on services. You can pretty much either buy, rent, or download any of today's TV shows, anyway, so I saw no point in going through a middle man.
