  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 >>
