I give it 5 stars for indoor antennas. I went from 7 stations and 15 channels to 17 stations and 43 channels. The furthest is +55 miles. Another is 42 miles... NO problem with either. However most of my stations are with in 22 miles and mostly in one direction. I would say if all your stations are out +40 miles this should work but you might start to thing about an outdoor Bow-Tie antenna. HOWEVER it depends on your house and terrain. If your house is wood, drywall, vinyl siding, with antenna near a second floor window facing toward the station, good to go. If you are in the middle of a brick building, no windows, you can expect less than spectacular performance (I am assuming). OUTDOOR antennas are always better, but I am very impressed. I am an engineer and my hobby is radio and antennas.Since most of my stations I care about are all in one direction I can just set and forget. However if your stations are scattered to the four winds it could be a hassle always having to aim it. Most stations are South East but one is West. It comes in no matter what direction I turn it. It is the strongest station at 17 miles. Two of the distant stations need the antenna to be aimed; they are in different directions and need the antenna to be aimed, but for the most part 90% of my stations are all in one direction.There is no real solution for stations in many directions, even with an outdoor antenna, which would need a "ROTOR" to turn it to different direction. With the Terk HDTVa the further out the station the more you have to aim it. This is OK and what gives the antenna it's power and low noise. However it is NOT an omnidirectional antenna. Typically omni directional antennas don't have the performance, as they are a compromise for convenience. You will never get range with an omni direction antenna. Even basic rabbit ears are bi-directional.The two petty gripes others always mention and I will repeat, is the base is narrow so it's tippy side to side. Also because the rabbit ears (the dipole whip antennas) are angled back, you have to give it room, 10" much more depending on the angle of the base to the wall and how wide you have the whips spread out. 

Question: How is the reception?
