[Amps] slug tuned variable inductors

[Joe Brown]

Is it possible to use slug tuned coils with any reasonable power? I am thinking of moving a ferrite slug in and out of a coil to change the inductance, but don't know if it would be too lossy at real power? Is there a type of ferrite that could be used for this at HF? Or is this just a goofy idea. I want to get rid of the roller inductor in my homebrew antenna tuner.

I read an article in an old Ham Radio magazine about a tank circuit for a commercial 5KW amp, and they lowered the inductance by moving a shorted turn ( a piece of copper pipe) in and out of the tank coil. Wondering if can do the same thing with ferrite.
