Anyone have any experience or knowledge they'd like to share regarding signal boosters for cell phones. Effectiveness, costs, applications? We recently moved to an area that has poor coverage. We are not much further from our previous home and actually closer to a tower than before but we are in a little pocket with a mountain to one side and the ocean on the other. Coverage improves dramatically a short distance away. We have intermittent low signals. I would be interested in reading about both home and marine applications.
