BTW, I have seen loop coupled antenna described but one of the pages I
found talked about the complexity of correctly coupling the antenna to
cables, not just impedance, but the balanced/unbalanced issue. This web
page seems to talk about it pretty well.

So many pages, so little time. I realize that the issues of coupling
are *solved* by using the loop coupling just like the ferrite core
coupling. Opps.

A fair number of LF loop antenna I have found don't bother with this,
but many do.

What will be the impact of not having an actual ground connection
anywhere? Will it be important for the shield to be grounded to a
"proper" ground to be effective? There will be no power line connection
for this device.
