I have this one (w/preamp):
HD Stacker TV Antenna - Best for weak signal
I have it pointed towards Canada/Windsor and get Toledo Ohio, Jackson MI, Lansing MI, Flint MI and of course Metro Detroit from my Ann Arbor location.
That's a huge 360 degree swath without rotation.
Of course weather can be a bugger, incoming storms from the west can mess up the signal from almost any other direction, but something always comes in.
I get more than double the stations than basic cable, and with no compression. This is the best picture and sound available, better than any cable, satellite or Blu-Ray player.
However, there are a lot of repeats as there are only so many networks.
I end up doing about half my viewing over the Internet on my computer. Large monitors are pretty cheap these days, and when you sit close they don't need to be as large as a TV.
Be careful on the radius and bends you put on the cable, the bigger the better. They can short out if too tight a radius.
I have the TV antenna grounded, the antenna pole grounded, and the signal cable grounded.
Ground it, you heard it here first.
The higher the better, that five foot pole they give you isn't tall enough unless you live on top of a hill.
