Abstract: A TV receiver preliminarily measures and stores, in a memory, data of best receiving directions, each giving maximum signal intensity, of a multi-directional antenna for receivable channels. When the antenna rotationally shifts physically for some reason, one channel is selected and subjected to measurements by an omni-directional scanning again to determine a new best receiving direction. A receiving direction number difference between the stored best receiving direction and the new best receiving direction of the same channel is determined. Using the receiving direction number difference for the one channel, all data stored in the memory are renewed at one time, the data being the best receiving direction numbers and the signal intensities therefor for all the channels. The antenna direction can be quickly adjusted to the rotational shift by new measurements for one channel, without requiring time to make unnecessary measurements for all channels, achieving a best receiving condition steadily.
