Abstract: The present invention is a communication system for transmitting an electrical signal from a transmission tower and includes a first transceiver located adjacent the base of the tower and which is in communication with a source of an electrical signal which is to be transmitted. An enclosure is removably located adjacent the top of the tower and includes a second transceiver for receiving the transmitted electrical signal from the first transceiver and a third transceiver for retransmitting the electrical signal from the tower. By this arrangement there is no need for stringing coaxial cable from a ground based transmitter to the antenna mounted to the top of the tower, thereby eliminating the power loss associated with the use of such coaxial cable.

Abstract: Disclosed is a supervisory control system for remotely monitoring and controlling at least one operational device. The system includes at least one microremote in association with an operational device and includes an input device for receiving a signal indicative of a parameter associated with the operational device and logic circuitry for controlling the operation of the microremote. A microcomputer is in communication with the microremote(s) by way of a communication link, and includes input devices for receiving the signal from the microremote, a memory device for storage of a program or algorithm, and a microprocessor for controlling the operation of the microcomputer and for utilizing the program or algorithm for operation of the supervisory control system. A personality module is removably placed in communication with the microcomputer and includes logic circuitry for controlling the operation of the personality module, and a memory device for storage of at least one program or algorithm.
