Abstract
A changeover device provides for contactless interchange of power between an r.f. source such as a transmitter Tx.sub.1 and two loads, such as an aerial 2 and a test load 3. The device may be used in a changeover system for exchanging main and standby transmitters in the event of failure of the main transmitter between the aerial and a test load, or for connecting transmitters in parallel in such a way as to leave them well matched in the event of failure of one while permitting half power operation from the surviving transmitter.
