[Amps] KK5DR's ferrite loaded plate chokes.

[Mike]

The Wikipedia entry looks okay to me, it's obviously written as a general
introduction to the Yagi Antenna for people that have no idea what one is.
I might not use sentences the author uses like "The reflector is easily
identified as being a "BIT" (5%) longer than the driven element.

The great thing about Wikipedia is that smart people like you Dr. David, can
input, change and make the necessary technical corrections.

It's amusing how much time the guy has devoted to writing about things he
knows 
little about. It would be a bit like me writing about brain surgery,
concrete, 
glues, flower arranging, or anything else I know next to nothing about.

Reading his background notes, it sounds like he knows a lot about welding.
His 
time would be better spent writing web pages about that.

I have an electronics background and try to not be overly critical of people

that do not. But when they go writing web pages, as if they are an authority
on 
the subject, it does get a bit annoying.

It is like the Wikipedia article on the Yagi-Uda antenna. Clearly written by

people that know next to nothing about them.
