Steps that describe the work of Repeater.

1 out of 5 eggsCell phone signal booster

Pros: Looks like it should be good

Cons: Does not work/can't tell it is on
Difficult to install as you have to run wire through attic
Signal is pulsating 0-1, 0-2,0-0, 0-1 bars, etc.

Other Thoughts: I live between two towers, 4.5 miles one direction, 1.5 miles the other way. I aimed it on both with the same results. No improvement!!!!!!
Throwing your money away on this one.
