TopCat, I'm attaching a pdf of the antenna and booster. I'm assuming you have the TV hooked up and coax going to the correct inputs. Then there's the task of figuring out which direction to aim the antenna. That little pointer on the ceiling is only a guide to tell you the position for lowering the antenna. It is pretty much 90 degrees off of the direction the antenna is pointing.
CLICK HERE for a website to help you determine where to aim the antenna for your location.
If your connected right and the antenna is aimed pretty close and you know how to have your TV scan for channels and still have problems, it possible there is a loose connection on the back of the booster. Worse case scenario, the cables are not connected to the booster correctly.
Come back and let us know how things work out. By the way, Welcome to the heartland Forum & Family.
