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. In one embodiment of the present invention, the second and third transceivers are conveyed to and from the top of the tower via a pulley arrangement for maintenance purposes, and in an alternate embodiment, the second and third transceivers are enclosed within a housing and are conveyed to and from the top of the tower within a conduit by means of compressed air.
