テレビジヨンダイバーシテイ装置。[Claims for Utility Model Registration] It has a plurality of television antennas, and the antenna input terminals are sequentially switched during the vertical retrace period of the beam, and the received electric field strength of the antenna connected to the antenna input terminal is checked. A television diversity device that causes the largest antenna to receive television radio waves includes: an antenna connection determination circuit that is provided for each antenna input terminal of the television and determines whether an antenna is connected to the antenna input terminal; an antenna selection circuit that sequentially selects the remaining antenna input terminals by skipping the terminals with no antenna connection during the vertical retrace period of the beam when there are terminals that are not connected; and the selected antenna input terminals. What is claimed is: 1. A television diversity device comprising: a reception antenna determining circuit that checks the reception field strength of the antenna connected to the antenna and causes the antenna with the highest reception field strength to receive television radio waves.
