50 microhenries of plate choke with the shunt plate tuning capacitor, and the
capacity of the loading capacitor in parallel (as it is connected through the
long lead that is the tank coil), bearing in mind that if the load is not a
resistor, but an antenna, at low frequencies, it will tend to look like a high
impedance.

We are not talking about 'choke resonance' where the choke with its inherent
distributed parasitic componets of reactance resonates, but of choke resonance
where the choke is tuned by the other discrete components in the circuit.
