I haven't heard much about the lava-2605. It comes with a built-in rotator which is a nice feature, and it
sells under $50, and that looks like a good deal for an amplified antenna + rotator combo.
The point is this. If you aim for Freeport and Rockford stations you don't need a rotator. If you are hoping to pull Madison, WI and Chicago stations, then you do need a rotator, but you also need a much more powerful antenna. I don't believe Lava is capable of picking TV stations 60-70 miles away, it is not a deep fringe antenna. However, any deep fringe antenna with an amplifier and rotator is over your $100 budget.
