ANTENNA JOINTING APPARATUS FOR TRANSMITING AND RECEIVING

摘要

The coupler has a shillding plate to shield transmission filter from reception filter. The frequency interference between two filters is prevented that the carrier wave transmission and reception are done instantaneous. The transmission and the reception filter are deposited in parallel in a spacing on a plate (4). A vertical shielding plate is deposited between the filters. A upper and a lower case covers the plate (4) except the front.
