Sure, but being the cap is a semi-fixed limited range device, you will
vary the number of turns in the loop to come up with the usable range.
The loop should be built around the cap. It's the part that is
unchangable within it's range. MK


True to a point, but I'm sure a tap or two on that coil may be
switched in or out as required. The gangs on a capacitor could be
switched in and out too, in conjunction with varying the portion of
coil used.
