AHA - now we have the answer to the problem of narrow yagi lobes.
We are simply using the wrong graph paper to depict the pattern.
I'm sure that with enough planning and dedication, a committee of a few
dozen could come up with a special graph paper, custom-made to your yagi
such that no lobes would seem narrow at all.
In fact, your yagi could become the perfect isotropic radiator.
THAT's the ticket.
For a 'more fun' way to plot yagi lobes, you must use a field strength meter
and a motorcycle and a blonde.

Amateur radio operators have been convinced to display radiation patterns
on logarithmic paper to make it look more directional than normal plotting
procedure.
Since I can now generate a complete circle for an non yagi antenna array
using logarithmic paper on my antenna program I thought it would be
interesting to see
what a circle would look like when using 'standard' graph paper.( a
reverse
procedure)
Now, as I write this, I realise that my antenna computor program has the
ability to
make this transition.
This will be interesting as I have no pre-expectations as to what it will
show.

I've got to now draw a circle with a compass and observe how the shape
changes when
replotted with logrithmic and other types of graph paper

Be sure to give us a report on creating the logarithmic graph paper.
If I heard someone was looking to replot circles on log graph paper, I
would
say he must be a ham.
Then I would think about writing a Java program to do it, as I slipped
into
sleep while listening to 'Coast-to-coast-AM' on the radio.
