The invention discloses a BD/GPS dual output antenna device. An antenna element (1) acquires a satellite positioning signal and then inputs the satellite positioning signal into a conditioning circuit (2). The output of the conditioning circuit is connected with a first amplifier (3) and then connected with a filter (4). The output of the filter is connected with a second filter (5) and then connected with a power divider (6). The power divider outputs two signals. The first signal is connected with a first radio frequency switch module (71). The output of the first radio frequency switch module is connected with a first interface (81). The second signal is connected with a second radio frequency switch module (72). The output of the second radio frequency switch module is connected with a second interface (82). The first interface is connected with a first voltage protection circuit (91). The output of the first voltage protection circuit is connected with a voltage comparator (10). The second interface is c
