The information you have presented is well stated , I Like That , Even though you do not know that much you are trying and you grasp basic information real fast , I Like That. Half power beam width is the beam width of the antenna , the angle from the center line of the length of the antenna that antenna ability to receive a signal drops to half. The half power becomes more noticeable as the antennas distance from the transmitter is increased because the signal is weaker. Half power beam width is good to know because the Tv stations off to the sides of the main stations to the front of the antenna , The half power helps one gauge / have a idea of how far off center the weaker or stronger station can be received. Beam width is also directly tied in with multipath, during the analog days of Tv reception ghosts were a real problem , Now with digital Tv the digital tuners have multipath signal correction and to a large degree the digital tuner will correct multipath and this is one of the many reasons that digital Tv has crisp clear pictures. The digital tuners work so well that now days clear pictures are received on the sides of the Tv antenna and the back of the antenna. During the days of analog only Tv Tv transmissions received at the sides and back of the antenna would produce unwatchable pictures the ghosts would be so bad. Can a digital tuner be overloaded with multipath ?? Yes and when it happens the picture will break up in to blocks and or just go blank.
