<p>A circuit for the selective activation of a plurality of antennas (L1 to L4) from a common end stage (8) contains a first selector switch (10) at a terminal (6) of the end stage (8), the switch contacts (12, 22) of which are each connected to a switch contact (20, 26) and via an antenna (L1, L2) each to one fixed contact each of a twin selector switch (14, 24). The fixed contacts of the twin selector switch are each connected via a further antenna (L3, L4) to the other terminal (18) of the end stage and these are also connected to the other switch contacts (16, 28) of the twin selector switch.</p> |
