“…In the FM path the erroneous peaks of the instantaneous frequency deviation are detected in a similar way. If both comparators indicate a distortion, then the antenna selector, realized by PIN-diode switches, selects the successive antenna [Lindenmeier, 1990]. is the precondition for the realization of a cost effective scanning diversity system.…”

The presented mobile multiantenna scanning diversity system for terrestrial TV highly improves the reception in cars making use of four active broadband TV antennas. The diversity systems for picture and sound choose independently from each other the optimum antenna signal among the four TV antennas based upon different diversity criteria. An indicator sensitive to the RF level evaluates the picture quality at the end of each video line. The TV sound is optimized by application of a diversity processor originally designed for FM broadcasting and is available now as an integrated circuit. This processor is sensitive to noise, multipath distortions, and three types of interferences: cochannel, adjacent channel, and intermodulation interferences.

“…Active window antennas [4] are becoming increasingly popular due to their hidden, aesthetic look and excellent reception performance compared to a whip antenna. The field tests in the vicinity of AM and FM transmit towers also revealed that these active antennas are less susceptible to intermodulation distortion when they are equipped with automatic gain control (AGC) circuits.…”
