| 摘要 |
The present invention relates to a searching apparatus, especially an avalanche transceiver, including a receiving unit (22) for receiving transmission signals for locating a transmitter and a transmitting unit (20) for transmitting transmission signals, wherein at least a first (10) and a second transmitting antenna (12) are associated with at least the transmitting unit (20), which are disposed in the searching apparatus oriented in different spatial directions, wherein only one of the transmitting antennas (10; 12) is in operation in the transmission mode, wherein the searching apparatus further includes: at least one position sensor (28) adapted to determine a spatial position of the searching apparatus and to provide a position signal on its output, which is correlated with the spatial position; and a switching device (16) coupled to the at least one position sensor (28) for supplying the position signal on the one hand and to the at least one first (10) and second transmitting antenna (12) on the other hand, wherein a first range of values of the position signal is associated with the first transmitting antenna (10) and a second range of values of the position signal is associated with the second transmitting antenna (12), wherein the switching device (16) is adapted to transmit the transmission signal over the first transmitting antenna (10) in the transmission mode, if the position signal is in the first range of values, and to transmit the transmission signal over the second transmitting antenna (12) in the transmission mode, if the position signal is in the second range of values. Moreover, it relates to a method for operating a corresponding searching apparatus.
