Continental Electronics type 377C-1A Exciter Control, 377D-1 Combiner Control and 377D-2 Transmitter Control units provide both automatic and manual RF switching for both AM & FM transmitter systems. These units can be mounted in a standard 19" rack, are compatible with most radio transmitters and provide an easy and uncomplicated way to achieve automatic switching for redundant exciter and transmitter operation.

The 377C-1A Exciter Controller is 2 RU high and uses BNC connectors for all RF connections and a barrier strip for all control connections.

The 377D-1 Combiner Controller operational modes include combined power to load, combined power to antenna, Transmitter 1 or 2 to antenna with the other transmitter to the load, and includes Plate On/Off and Manual/Automatic Operation. The 377D-1 is 3 RU high, also uses BNC connectors for all RF connections as well as barrier strips for control connections.

The 377D-2 Combiner Controller is operationally similar to the 377D-1 controller but differs in that it is meant to control two transmitters in a Main/Alternate, or "Hot Standby" configuration. The 377D-1 is also 3 RU high, also uses BNC connectors for all RF connections, and also uses barrier strips for control connections.
