Definitions

the antenna 1 is grounded as usual and hasconnected thereto a source of high frequency oscillations which in this case consists of the high frequency alternator 2.
This may be inductively connected to theantennaby means of frequency is placed in series with the antenna.
it may be desirable to connectthe source of energy to the antenna by loosely coupling the primary of transthis inductance. Ifthe antenna is comparatively smallthe value ofthis inductance required to givethe proper tuning will be correspondingly large and as aresult .there will be a large difference of poterminals ofthe inductance.
