This is a dumb question for anybody.
Suppose I had a Yagi antenna and the elements needed to be cut within 2 mm. The original elements are essentially crimped at the end and are made of a rolled tube which won't really hold water.
Now say, I want to replace one of the elements with a tube of the same diameter for whatever reason and want to place protective end caps on the ends so water doesn't get in.
Is the "electrical length" the length of the metal or the length of the metal less the amount covered by the insulator?
Does it matter depending on the element;s function? Reflector, director or driven element.
