Interchangeable antenna

Hi to all,

I'd like to build some antennas for 125KHz with different inductance. On my PM3 I have 1nF for C. How do I connect new capacitor for increase/decrease the value of C?
Which is better parallel or serial connection?
I'd like to put the new capacitor in the antenna so every antenna has the own capacitor.

This connection should be OK. But I don't how to calculate new C.
