[TenTec] Re: Rudimentary SWR question...

[Bill Fuqua]

By the way this is my 30 year as an electrical engineer. I got my ticket in 
1961.
The problem is many people have simply have stopped asking the questions of 
why and how things work. They have a great deal of experience but 
sometimes  little real understanding. Too much is lost by  just doing the 
math and solving the equations. Frequently people know the math but don't 
understand what it really means.
Start thinking folks and asking questions and looking for the answers. This 
issue came up when a student of mine asked a very simple question. That was 
"Why is a half wave dipole a half wavelength long?". To you it may seem to 
be a stupid question but it is one that should make you think.
