PROBLEM TO BE SOLVED: To provide transmission equipment in which switching can be made without hit in the fault of a transmitter and is suited to sharing among plural programs in particular while conventional transmission equipment has a problem of generating hit when switching to a reserve transmitter when an active transmitter is broken. SOLUTION: When a No.1 transmitter 1 and a No.2 transmitter 2 are normal, transmission output is composed and outputted by a composing device 14 via a distributor 6 and a switch circuit 10 and via a distributor 7 and a switch circuit 11. When the No.1 transmitter 1 is broken, the transmission output of the No.2 transmitter 2 is composed and outputted by the composing device 14 via a distributor 7 and switch circuits 9 and 10 and via the distributor 7 and the switch circuit 11. When the No.2 transmitter 2 is broken, the transmission output of the No.1 transmitter 1 is composed and outputted by the composing device 14 via the distributor 6 and a switch circuit 101 and via the distributor 6, switch circuits 8 and 10.
