In a TV broadcast signal receiving system, setting up of a multi-directional antenna and a TV broadcast signal receiver is made simple and easy. The multi-directional antenna identifies a standard direction used as a standard for receiving a TV broadcast signal, at least latitude and longitude of a location of the multi-directional antenna. The TV broadcast signal receiver memorizes TV tower information including position information of latitudes and longitudes of positions of a plurality of TV towers and channel information of channels, TV broadcast signals of which are transmitted from each TV tower. The TV broadcast signal receiver decides an optimum signal receiving direction of each receivable channel with using the antenna information and the TV tower information, which is used for switching an effective signal receiving direction of the multi-directional antenna for receiving a TV broadcast signal of an optional channel chosen by a user.
