Query: Worked well

I bought this for our bedroom TV, knowing that based on the construction of our building and the distance from the windows that it would be a tough spot for reception. It picked up all the stations I really wanted, can't get others that fortunately I'm not all that interested in. There was some dropping of signals. I'm going to replace it with a db4 and use it in the living room where it gets everything and rarely drops signals.
