Abstract
An apparatus directs two high-power UHF transmitter signals to one or the other or a combination of output destinations as determined by the setting of control components. Redirection between outputs can be performed continuously under full power. Using the apparatus, synchronous amplifiers directed to the same output produce a signal with all of the power of both amplifiers. The signals can be shifted to the station load without shutting down the amplifiers. After a failure, the remaining amplifier can be redirected to provide a clean signal.
