the flow of the current in the an-tenna circuit is not seriously reducedthereby. Conductive coupling of the closedand open oscillation circuits is shownin Fig. 107, where an auto transform-er is employed to transfer the oscilla-tions to the antenna. In this diagramthe turns from A to B constitute… … Fig. 107—Conductively Coupled Transmitter. Oscillations of radio-frequency are thus induced in the secondary circuits. Theadvantage of this method of coupling lies in the simplicity afforded by the useof a single helix lor transforming the oscillations. The inductively coupled sys-tem, on the other…
