I suggest making a simple loose coupler.  That is a
relatively large fixed coil with a smaller coupling coil that can slide over
it. The small coil is used to couple the antenna.  you need a large coil of
sufficient inductance to resonate with the variable condenser you have.

When I was playing with different designs, it seemed to me that an inductive coupling to the antenna lead was significantly less noisy than when I used a capacitor to couple to the antenna lead.
