摘要

Circuit for selectively driving the plurality of antennas (l1 to l4) of a common output stage (8), containinga to a terminal (6) of the output stage (8) lying first switch (10), the fixed contact is selectively connected to one of two switching contacts (12, 22) is connectable,a second change-over switch (14) with a fixed contact, which via a first antenna (l1) with a first switching contact (12) of the first switch (10) is connected, a first switching contact (16), which is connected with the other terminal (18) of the output stage (8) is connected, and a second switching contact (20), which together with the first switching contact (12) of the first switch (10) is connected,a third, simultaneously with the second changeover switch (14) switchable changeover switch (24) with a fixed contact, which via a second antenna (l2) with a second switching contact (22) of the first switch (10) is connected, a first switching contact (28), which is connected with the other terminal (18) of the output stage (8) is connected, and a second switching contact..
