Robert, your first sketch, the inductor and 16NF capacitor are a parallel tuned circuit, so when its at resonance, its high impedance, so when you feed it you need to feed it from a high impedance circuit and have lots of volts to drive current into it.
If you break the earthy end of the 16 NF capacitor, and insert a 160 NF capacitor and feed your 50 ohm source across that capacitor, the tuned circuits impedance appears to have fallen to 1/100 of what it was before. Unfortunately if you needed 16 NF to resonate the inductor, then you now have only 16 NF - 10% (capacitors in series) resonating the inductor. So the transformer action is slightly different.
