I have a simple question about general meaning & importance of the coupling capacitor in following part of a simple receiver circuit:

enter image description here

Is it true that the proper reason why this coupling capacitor C2 is there is simply because it should form part of the bandpass-filter C2-L1-C1?

enter image description here

Or does my interpretation hardly missing the point?

The capacitor C2 would be of a value small enough to prevent the antenna from damping the Q of the tuned circuit.

In other words, the purpose of C2 would be to improve selectivity.
