Kurt,

Yes, more than 2x the calculated skin effect depth would be best.
But have a big roll of foil bought for EMI use that is only 1 mil thick, and would probably use that.

A skin effect depth of 0.6mil means that all but 37% of the 14mhz energy is in that top 0.6mil.
So if we are aggressively conserving copper, a 1 mil thickness of copper at 14mhz is?
making good use of all the copper (both sides), though effective resistance at 14mhz is somewhat higher
than it would be if it were 2 mil.? If I care, I can go twice as wide with my cheap 1mil foil.

A loop built of 1 mil foil would be impossibly floppy, hence the plan to stick it to the laminate strip.
The question remains if the laminate strip will have some sort of adverse effect.

Amazing what you can do on 50mW with slow digital modes.
Can't imagine a few mils of teflon deteriorating at that kind of power level.

I find extremely low power messaging over long distances without dependence on any infrastructure
to be compelling, and potentially very useful.? Even if it takes several minutes to say "We are all OK".
Having it fully portable makes it even better.
That will most likely continue to be an EFHW for me, but mag loops are very cool.

Picture looks fine, by the way.
I'm curious what you arrive at, especially for the capacitor.
