Advertisements For OTA, the game changes a bit. For what you describe, you are likely experiencing multipath. What kind of antenna are you using? If you station location allows, a more directional antenna but with just enough gain would likely be the best choice so as to attenuate/reject off axis reflections. Im using a yagi with corner reflector. It has a narrower beam width than a bowtie type antenna. As the weather changed, I had to turn my antenna about 10-15 degrees to eliminate some newly appeared dropouts. You might try doing some re-aiming. For all its other issues, with analog TV you could usually identify the problems fairly easily since ghosts, snow etc were pretty easy to see. With digital TV, its a whole new ballgame.
