compare favorablywith modern methods of excitation. Indirect methods of antenna excitation are shown in Figures 106 107 and 108. Theprincipal advantage of these methods of coupling lies m the fact that the closed rcuit con-denser acts as a reservoir of energy and since the capacity of the condenser… … W I Fig. 106—Inductively Coupled Transmitter. 94 PRACTICAL WIRELESS TELEGRAPHY. voltage which results in the production of more powerful oscillation. Then by proper adjust-,ment of coupling, these oscillations may be transferred to the antenna systems at a certainrate and radiated in the form of…
