PURPOSE:To enable broadcast and communication without interference between districts, by locating the beam distance with narrower distance than the beam width and establishing the polarization by about beam width toward the direction orthogonal to the beam train. CONSTITUTION:The feeder in the feeding box consists of the transmission and reception brancher 17, distributor 18, and power distributor 19. The brancher 16 is connected to each horn 13a...13e, 13a'...13e', and the signal branched is branched into channel or channel group with the brancher 17. Further, after the signal in one channel or group is synthesized with adjacent brancher 18, the output is fed to the power distributor 19 and given for the specified distribution ratio. The beam distance is located with narrower distance than the beam width and beam polarization by about beam width is made toward orthogonal direction to the beam train. Thus, broadcast and communication are made without interference between districts. |
