Thank you Stan. Living in a valley. the signal is over 1500 feet higher in their "line of sight". Also the tower is 7.5 miles away. I have been looking at boosters, as both phone companies say they are not interested in increasing signal strength into the valley due to "lack of profitability."
The companies offered several different booter models and makes but all start at $300 and go up. I really hate paying their rates and then have to pony up more money just to use the system at home/shop. I do not have this problem outside my valley.....usually. I will investigate your information though.
