Hi Arthur,

Let's make this practical for 2M. The skin depth there is all of 30
millionths of an inch and we can talk about a tube with maybe 100
millionths of an inch wall thickness, so let's make it a tube with a 1
thousandth inch diameter with the conventional length of 39 inches.

What size fuse will blow?
