I find it a annoying and a pain to climb up to the roof and adjust the TV antenna so that I can watch my favorite TV program without distortion. I am not using satellite service which requires a dish to capture the signal and I know the antenna is designed to receive radiowave signals from the nearest broadcast tower and my TV will be tuned to a specific frequency. My question why does the orientation of the TV antenna in-situ affect the picture quality?
