Abstract
Antennas ( ) are disposed within an antenna body ( ) of an antenna system in such a manner as to receive UHF band radio waves coming to the main body ( ) from a plurality of first, different directions around the main body ( ). Combinations of the antennas ( ) makes the antenna system possible to receive UHF band radio waves coming to the main body ( ) from a plurality of second, different directions between adjacent ones of the first directions. Switches ( ) disposed within the main body ( ) select one of outputs provided by the individual antennas ( ) and their combinations. An antenna controller ( ), a unit separate from the main body ( ), supplies a selection control signal to the switches ( ). The antenna controller ( ) provides such a selection control signal as to successively select the direction of the radio wave to be received in the clockwise direction about the main body ( ) each time a first operating element ( ) on a remote control ( ) is operated, and provides such a selection control signal as to successively select the direction of the radio wave to be received in the counterclockwise direction each time a second operating element ( ) on the remote control ( ) is operated.
