In a receiving apparatus and a method for setting a receiving antenna thereof, for dissolving a problem of necessity of a large amount of time for channel search, since it needs a time for setting up the receiving antenna at each physical channel, in the channel search operation, including searching of receivable channels and also memorization of an optimal setup for each of the receiving channels, receiving conditions are obtained for all of the physical channels in each of the setups of receiving antenna, and this obtaining of the receiving condition is conducted on all of the setups of the receiving antenna. In that instance, a number of times of controlling the setup of receiving antenna is determined to be a number of combinations of the setups of receiving antenna, and thereby shortening the time necessary for the setup of the receiving antenna and the time necessary for channel preset.
