If you've tried all positions with antennae, booster switch is on, and are sure you have all settings on TV correct, try running an alternate cable directly from antennae head to back of current plate where your co-ax from antennae is attached. That will tell you if you have a bad cable or connection from antennae to plate inside. Just get a piece long enough to go through door or window to current spot where connected. If that doesn't cure it, then it's a head or booster switch problem. You can even by-pass the booster and go direct to TV to see if any better.
