ABSTRACT:
The disclosure relates to broadcasting by means of rotary antennas using rigid dipoles. Each of two distinct channels passes through the joint between the fixed support of the mobile part of the antenna and rise vertically into the interior of the mast to respectively reach two distinct vertical groups of dipoles. It is thus possible to carry out two simultaneous transmissions from one and the same rotary antenna. Application to broadcasting in decameter waves.
