For those of you having problems with this unit you must remember that the indoor unit uses the same frequency to talk to the cell phone that the outdoor antenna uses to talk to the tower. If the inside unit transmits and the outside unit picks it up the inside unit will lower its power until there is no feedback loop, degrading performance. So, if you can put the inside unit someplace where it will operate at full power and not interfere with the outside antenna then you are set. Try putting the inside unit in the basement or at the opposite end of the house. Also you will never get a better signal inside than what the outside antenna gets so put the outside antenna where it gets the best possible reception. That sounds obvious but I'm sure there are some folks that put the outside unit out a window and the inside unit next to it.
