There are band transponder boosters, pretty much applies a LNA across a whole bandpassed cellular band(think like the LNB you receive with in your satellite dish) and output a weak amplified signal in your house. You could try to make one or they are about $100 and work pretty well though sometimes a nearby cell will freak over the received signal fake 'echo' it makes. Works better with a good on-band dish or yaggi antenna pointed at the tower on the receive side.
