Hi all:

I just obtained a Loading Coil from a Gates ATU. The coil has a movable " Disc Plate " inside the coil.
The Coil was mounted with the tuning shaft going through the bottom of the box, and the tunable end was grounded.
Since it has no effect on Inductance when adjusted, can I assume that the disc varied Capacitance when mounted
inside the GATES tuning unit box ? Below are a couple of links to pics of the coil : Thanks for replies :
