> > Cleaning the outside is easy. How do you clean the inside of those
small diameter elements?
Why would you need to do that? RF observes the skin effect and only
travels on the outside of the conductor. I always thought skin effect
meant it flowed on the SURFACE of a conductor.
How does the RF know if it's on the outside surface and not on the inside
That's easy. It spills over the ends into the tubing. Would you believe
since the tubing is open on the end, it reflects a dead short 1/4 WL down
inside the tubing where it shorts it out. Reflector and director are
slightly reactive but it also cancels out. K7GCO
