And to include some closer to on topic content - has anyone here
experimented with using a slinky as a loading coil for a "portable"

dozen or so members tried it. With, as you'd expect, mixed results.

field. As a loading coil for a vertical, not so much. Largely
because it needs a form to keep the coil stable.
Would sheets of plastic inserted between the coils to prevent contact
plus an overall clamp to maintain shape do the trick? *Once done, it
could be 'set and forget'...
If I go this route, I'd be looking to stretch it out a bit so I can tap
it at different spots for different bands.- Hide quoted text -
