I am trying to understand how exactly to tune the Superhet receiver. In my simulations, I have attached to the initial frequency mixer---> A local oscillator and an AC signal source to model the incoming frequency.

Now my question is how will this wanted frequency reach the mixer from the antenna ( Since antenna is exposed to all frequencies ) ?

Do i need to add an additional tuning circuit or will this be sufficient ?

If an additional tuning circuit is needed, how will I co-ordinate the oscillators attached to them ( since both of them will require different frequency).

I believe gang capacitors come into this play ( not sure) but I have only this piece available ( nothing else) :
