Is there an area near your home that has any cell phone signal? If so, perhaps one of these would work..


With a couple of these..


The repeater usually operates on 5-9 V.D.C. @ 1-2 amps which can be easily operated on solar power in a remote location. (Possibly on top of a hill) Aim one antenna towards a signal source (Cell Tower) and the other antenna towards your house. Keep 2-3 hundred feet separation between the antennas for best results.

Food for thought..
