I've done exactly what you are proposing and the results are not impressive
but at times can make the difference between making a call and not being
able to. It is most affective when you're within a few feet of the indoor
antenna and the outside high gain yagi needs to be pointed correctly or it
can be useless or even worse than using a vertical antenna.
The results using an amp in line give a little better results but never what
is claimed by the manufacturer.

Subject: [RFI] Passive Cellphone Repeater?
It seemed to me that someone here will know about this ...
We are in a steel building and have been using a Samsung Internet-GPS black
box to generate a cellphone signal.
However, whenever there is a power glitch (three times today due to high
wind gusts in the area) we lose the connection.
If we go outside we can get a signal off the tower.
SO ...
Has anyone rigged a passive repeater using a gain-type outside antenna and
an omnidirectional inside antenna with only coax connecting the two
back-to-back?
It seems as though that may be more reliable than the black box device ...
if it works.
WDYT?
