Abstract
A whole wave antenna is placed on an insulating support and has its feed input located a little above its middle. In order to reduce secondary lobes inductive reactances are serially inserted in the antenna on each side of its feed input so as to produce a rapid rotation with inversion of the phase of the currents on each side of the feed input.
