遠隔アンテナ切換システム
Document Type and Number:
Japanese Patent JP7203455
Kind Code:
B2
Abstract:
To provide a system in which a configuration of an antenna switching receiving device is simple and a desired antenna switching can be performed reliably in a remote antenna switching system for connecting between an antenna switching transmitter and an antenna switching receiver with multiple antennas connected with a single coaxial cable.SOLUTION: A first antenna switching transmitter 10a superimposes an encoded tri-level signal onto an RF signal to be an L signal when a clock signal is 0, an M signal when the clock signal is 1 and a data signal is 0, and an H signal when the data signal is 1, based on the clock and data signals for selecting an antenna. A first antenna-switching receiver 20a decodes the superimposed tri-level signal and selects and connects a designated antenna.SELECTED DRAWING: Figure 1
