"Why sever the connector? If we are talking about RG-213 size coax, that is .405 inches in diameter."


Sever the coax. I assumed the desired spot was far from the shack and it would be too much trouble to fetch the end of the coax and then wind the whole length several times through a large core. But maybe not! And maybe installing connectors isn't that much trouble for someone good at it (I'm not). I'd just want to be sure I had the right spot first.

A quick model of the two-wire current shunt didn't look that promising, at least for the initial geometry I picked. I'm not sure the idea is worth pursuing.
