Willing to spend $500 to $1000 a site? If so, you can get an active
booster, which consists of a fixed outside antenna (directional, if
you need that, pointed at the best line of sight tower), an inside
antenna, and a bi-directional amp to link the two together. The
antennas are easy; the amp is hard (and if you could build it, you
wouldn't be asking us.). There are perfectly good commercial products
to do this.
(And, unrelated to the technical problems, the cellular companies are
working very hard to get them banned, so they can rent them to you at
exorbitant prices.)
