Topband: Fw: Short Bogs

[Roger Parsons <ve3zi@yahoo.com>]

Tom was not referring to the sheathing on a cable but to the velocity factor of 
coax. Not the same thing at all.

It is well established that covering a cable with a dielectric will change its 
electrical length. The late LB Cebik's site (which is still accessible) 
quantifies exactly how much with different dielectrics. It can range up to 
about 7 %, and in my experience LB's figures are spot on.
