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?


What ever you want.There is nothing more to discuss
with you. Send what you refee to as your missives elswhere


Hi Arthur,

So basically you are telling us you don't know how to distinguish a
hollow conductor from a solid one based on practical testing
demonstrating how an hollow conductor will "blow a fuse when RF is
applied to it." [No one is surprised you can't perform this.]
