Is remote tuning an option?

Thinking helically loaded elements with an adjustable piece of short
metal pipe around each element half, or a metal rod inside the turns .
Move the pipe(s) towards or away from the feedpoint/centre. Using string
of course!

Could also put an adjustable C across the feedpoint?
