Abstract

A high-frequency switch for directional aerials, has stacked sliding contacts 3a and stationary counter- contacts 8a-12a. A balanced feed 2 is connected, by way of the sliding contacts to pairs of the stationary contacts for selection of phasing conductors 50, which are connected to dipole feed conductors 4a, 4b or 6a, 6b in a balanced manner. <IMAGE>
