Except that the gap in the stationary coil would be smaller, and the link

This brings up a thought I've had about link coupled tuners, of which I use.
Of course I feed the 50 ohm coax to the link. The center to one side
of the link and the shield (ground) to the other. What effect does
the "link position" have on a tuner? I suspect the link position
(mine is rotatable) would affect the matching impedance to the coax?
I think that'd be a WA5BXO question. He built his own link-coupled
tuner, yet the link was 'stationary' and didn't move, or rotate.
He also had several taps on a healthy piece of air-dux coil-stock. The
'link' was wrapped -around- the air-dux, with matching taps on the
opposite side of the air-dux.
Two sets of switches to move the taps in/out as needed for frequency,
and two capacitors.
