Does anyone have trouble getting the satellite radio signal to come in strong and consistent? We live in Sanibel and the signal has been a problem. My radio and antenna are located inside the house, and I've heard that concrete blocks can cause a problem. I just purchased a new Pixel Pro 600 outside antenna to mount on the back of our home, and hope that solves it. It's a one foot long antenna that mounts to the outside wall and an RG6 cable is then run from the anntenna through the attic, to the receiver. I already have an email from the VCCD that it is allowed. Any thoughts or similar experiences?
