We have no cell signal in our house, and only 1 bar of signal out on the driveway, so I called Powerful Signal to see if they could help out. The technician was very helpful. We had several email exchanges. He told me how to get the actual signal strength on my iphone, and how to go around the property to find out where the signal was the strongest. Then he recommended a system that he felt would help. It arrived on August 25,2023. I tested it out the next day and I was able to get enough signal inside the house to make and hold calls. I am not finished with my testing and adjusting the antenna (both height and direction), but I feel in the end the system will work for us.
