I live in Loves Park, about 10 miles E of the HD transmitters. Indoor reception was spotty, erratic and frustrating. So, I went with a 5 element dedicated Yagi on a 10 foot rooftop pole for channel 13 and a 4 bow tie for channels 17, 23, 39 lower down on the same pole. These two antennas have separate lead ins and are positioned at slightly different spots on the azimuth to point more directly at their respective transmitters. Personally, I would not fool with an indoor amplified Terk antenna. Get a robust outdoor antenna mounted up as high as possible and you should get much better reception. Also, if possible, you might try moving the outdoor antenna a few feet back and forth and left and right to, perhaps, find the "hot spot" where reception is the best.
