Hi
For what it's worth multi turns loop inside a shield is a very bad idea
There is very high capacity between turns and the tuning range is small with usual variable
capacitors.
Instead it is better to use a single turn and add a good fixed toroidal inductor in serial .
By switching this inductor the tuning range can be extended upward limited only by the physical
size of the main loop.
