The WT4 millimeter waveguide system: The WT4 repeater station

The WT4 repeater station is discussed from outside plant construction, building construction, Western Electric installation, and operations viewpoints. Unique properties of the waveguide medium have necessitated the development of a utility tunnel for interfacing the waveguide with the diplexer array. The utility tunnel and associated waveguide hardware for termination are discussed. The diplexer array assembly and water-cooled repeaters placed further requirements on the above-ground portion of the building. A method of incorporating these requirements, as well as providing ancillary support equipment for the repeaters, is also presented. Future areas to be investigated, notably the use of a modular prefabricated building, are also explored.
