Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To facilitate installation works and to improve radio wave radiation characteristics by providing a radio section in a coaxial outer conductor and a skirt of the coaxial outer conductor around an antenna. SOLUTION: A skirt A20 whose length is equal to a 1/4 wavelength of a radio carrier sent from an antenna A6 in an outer conductor A19 is resonated with the transmission radio carrier, and the antenna A6 and the conductor A19 are insulated. Similarly a skirt B21 whose length is equal to a 1/4 wavelength of a radio carrier sent from an antenna B12 in the outer conductor A19 is resonated with the transmission radio carrier, and the antenna B12 and the conductor A19 are insulated. Thus, it is prevented that a high frequency current resulting from the carrier flows between the conductor A19 and the antennas thereby preventing the coupling between the antennas. That is, a carrier fTX1 from a transmitter A8 to an antenna multicoupler A9 is branched by a branching filter A23, an adjustment device A24 adjusts the amplitude and the phase into a carrier fTX11 .  When the carrier fTX1 received by the antenna B12 is sent to a synthesizer B25, the carrier fTX11 is synthesized with the fTX1 to cancel the carrier fTX1 so as to prevent coupling between the antennas.
