Anyone with experience regarding cell phone signal boosters? They
range from the joke printed circuit stickers which are pasted to the
back of the set to expensive 3 watt units.


Any brands to avoid? Anyone other than the Holland Michigan guy ever
get brain cancer from one of these things?


It has to be a non direct connect unit, as the phone has no removable
antenna. Are there still 'bag phones' available? They were pretty
powerful if memory serves.


Any insights, or circuitry for a home brew unit would be appreciated.

Just a FYI, GSM is limited by timing, not signal strength. I don't
know about CDMA.


Bag phones are analog. Lotsa luck finding service.

Latest is Drivers Looking at their iPhone Screens
?GPS? while Driving; saw one today and wondered
what he was doing with something in his right-hand
in front of his face just over the steering-wheel.
Luck for him the Stop Sign was for the Cross Traffic
and he managed to keep it centered in the TH Arch
but slightly on the white-line.
