ABSTRACT:
In the illustrated embodiments a dual branching is coupled to two simple branchings via coupling elements which are rotationally symmetrical so as to accommodate different spacial dispositions of the two simple branchings while maintaining electrically completely symmetrical passageways and consequent phase synchronism therein. When the dual branching is connected with an antenna for directional or satellite broadcasting operations, the sending and receiving frequencies, with respective polarizations at the respective simple branchings, may be separated with the use of a bandpass arrangement and 3-dB directional couplers for the respective separated frequencies.
