行なうことができない。(Prior Art) When communicating with a remote location using a transmitter/receiver having a transmitting/receiving antenna at one end of a coaxial cable, it may not be possible to obtain sufficient electric field strength depending on where the transmitter/receiver is installed. One option would be to extend the coaxial cable and install the transmitting and receiving antenna in a location with good electric field strength, but this is not possible under the current system.

いう問題があった。(Problem to be Solved by the Invention) As described above, in the conventional method described above, a plurality of transmitters and receivers must be installed at each location where the antenna can obtain a certain degree of electric field strength, which increases the number of locations where the antenna is used and requires the number of transmitters and receivers. There was a problem in that a large number of units were required to be installed, and costs could not be reduced.

To provide an excellent transmitting/receiving device capable of transmitting/receiving to/from all locations with a single transmitter/receiver even when transmitting/receiving through many locations where electric field strength is not sufficient.

手側と送受信できるという効果を有する。(Function) The present invention has the following effects due to the above configuration. That is, a high frequency input received by an antenna connected to one end of a coaxial cable is output to the coaxial cable as an electrical signal, transmitted through the coaxial cable, and input to an antenna connected to the other terminal. Since the antenna is reversible, the input electrical signal is radiated again as a radio wave, so it has the effect that radio waves from a remote location can be transmitted and received with a single transmitter/receiver device.
