“ You can see how important it is to have the leads short that you may not lose energy. By short, I mean about a foot for each connector. In your case, the leads are probably five feet long on an average. If you had placed your oscillation transformer, gap, and condenser close together, it would have been possible to cut the length of the connections down to two feet. Suppose you had placed the oscillation transformer directly above the condenser and near the side of the condenser there would be room for the rotary. ”

“ This means a fairly large degree of coupling between the primary and secondary of the oscillation transformer. Too close coupling will make your decrement high and this is hardly desirable. To make the secondary circuit absorb the greatest amount of energy, you must make its wave length equal to the wave length of the primary circuit. You see, it's a very neat little arrangement. The primary circuit is nothing but a condenser, gap, and inductance. ”

“ The longer you make your inductance, the greater will be your wave. This means, if you have a great many long leads connecting the condenser, spark gap, and oscillation transformer, you will build up the wave and will lose energy in the long conductors instead of centering it in the primary of your oscillation transformer. ”
