Hi,I've been studying resonance and as a general question as to applying them, where is the output point? I've shown here as antenna input but it could be any input signal. Where would be the proper take-off point to say an amplifier? Also what are the merits/disadvantages between series and parallel?

Hi,Thanks Al. I looked at several "Antenna Tuner" circuits and for the parallel tank circuit, it seems that the output point can be at any node point for the circuit. I also see many RLC variations of PI, L, etc. used for frequency input schemes. Some with a single variable cap and some with multiple and variable cap far more prevalent than variable inductors. So it does seem to not be a simple answer that I was looking for.

A parallel tank develops a high voltage across the inductor at resonance]
---> Just contrary, sorry, the serial tank makes kiloVolts. Im using it everyday and know for 1000% sure. Parallel generates kiloAmperes instead.
The answer is simple the ' output' is a point that has a minimum effect on the resonance.I've been studying resonance and as a general question as to applying them, where is the output point?

Yes however; SamR is talking about antennae the first step is to 'amplify' the signal. (achieve a maximal Q for that frequency)Hi,,
Sorry to disagree but it depends on the design.
That is, circuits are designed based on known configurations which dont pay much attention to frequency change, but do take into account loading factors.
