That's true for a solid conductor. I don't think you can apply that to
tubing. Both the inside and outside surfaces are "surfaces." I'm no
physics
professor, but I'll bet the "skin effect" applies to both surfaces. If
not,
telescoping elements would not be very efficient, if it worked at all.

Steve: Metal plugs have been used in the ends of the tubing and--there was
no change in the pattern or SWR. RF inside the tubing is called "Stealth
RF"--you never see, taste, smell, hear or feel it. If it gets out it looks
like Lightning, tastes like Salt, smells like Ozone, sounds like Thunder and
feels like Hell. Maybe it's leaky tubing that is responsible for "Long Delay
Echoes." Would you believe the diameter of the tubing also affects the audio
bandwidth like organ pipes. K7GCO >>
