Abstract
A distributed antenna system is provided which is formed from a series of modular stages interconnected by cables. Each stage may include an antenna, a filter, a compensating amplifier and preferably elements for impedance matching to connecting cables. Connecting stages also include a coupler for combining the output from the stage antenna with the output from the preceding stage and passing the combined signal to the stage output. Where the stages are part of a transmitting system, the coupler is replaced by or functions as a splitter, an input thereto from, for example, a preceding stage, being applied to the stage antenna and to the stage output.
