TUNNEL DISTRIBUTED CABLE ANTENNA SYSTEM WITH SIGNAL TAPS COUPLING APPROXIMATELY SAME RADIATED ENERGY ABSTRACT A distributed radio antenna system for extending radio communications into confined regions into which external radio signals do not penetrate, the system having separate transmitting (Tx) and receiving (Rx) antenna systems. Each Tx or Rx system has an elongated low loss coaxial cable system (18 or 31) and a plurality of antennas (23 or 28) connected to each of the individual segments of the cable system at spaced distances along the length of the cable segment. The antennas are coupled to the cable segments by signal taps (21 or 21') having adjustable or preselected values of attenuation so that the power fed to each Tx antenna (23) from the Tx cable system (18) is approximately the same and so that the attenuation of the signals received from each Rx antenna (28) is approximately the same, thereby conserving power and reducing system cost. The Rx antennas (28) are located generally intermediate to the Tx antennas (23) so that spurious and intermodulation signals are substantially diminished by space attenuation.
