In my home in Houston I get virtually no signal from TMo when indoors.
At a window I get 5 bars and I can actually see the cell site from my
front yard. The problem is that my house is built of stucco applied to
a metal lath that covers all but the roof, doors and windows of the
house making it a virtual Faraday cage.

I have found several options for wireless repeaters that will receive
the strong outdoor signal via an external antenna and then repeat the
signal through an internal antenna. Prices range from about $250 up to
$1000. Cost is a consideration but performance is most important.
Anybody here have any experiences to share?
