I was driving past N6MJ's casa today and admiring the good ol' KLM
3ele 40-meter beam.
I understand that the linear loading makes the antenna elements
electrically resonant while being physically shorter and more
manageable. But what does this do to the wave front/pattern coming
out the front of this beast? I would think that it is a compromise
overall and certainly a compromise when compared to a full size yagi,
but is there a right or wrong way to linear load a yagi?
In other words, is there some magic percentage of real length over
loaded length? Should the physical length be at least a 1/4 wave or
possibly .43625 of a 1/2 wave? (I just made up that number by the
way) Should the "tips" be longer or shorter than the initial element
with the loading making up the difference? Should each make up 1/3
of the length? Is it better to "end load" the element and only leave
enough "tip" to tune? Can you have too much loading?!
I'm sure a lot of thought went into how to properly "linear load" an
element, and I'm just curious what the answer is.
