The idea of 'reflectors' is perhaps the wrong approach, I prefer the term
deflectors
as one sees when rays hit a knife edge. Also close coupling enables elements
to
be current heavy and others voltage heavy such that it would appear that a
element was doing nothing when in fact it is the link for more current
loaded elements
in cluster form. A wall that you suggest can indeed reflect and absorb radio
waves but a
wall is beyond my means thus resonance remains a important function of
change.
But then close coupling of elements together with the deflection aproach has
been
dissed many times over the years with me and always ends in derision of the
author
Time will tell but experimentation can be enjoyable especially when a trail
of past results
suggests that my rubicon is at hand and close to submission to RADCOM where
experimentation is still valued.

Heh, no politics here or religeon so all can join in without fear especially
those who are willing
to consider and pursue 'outside of the box' ideas that others distain., in
order to gain better
understanding

Roy allow me to be a bit more directive regarding my pursuit.
I am trying to see what methods that can be used for maximum gain.
Having made many a long boom yagi 80 feet and 13 elements I have
come to the cinclusion that thinking must move away from Yagi's.
If one starts with a balloon squeezed in the center we get the figure 8
pattern.
I think we all can agree on that
My logic is that we must find a way to move all the volume at the rear to
the front thus increasing
the front diameter before we begin to massage it. The present thinking is
one sqeeze at the rear
is the best that one can do. It is here that I part company with the norm.
If we move all the volume to the front then talk of gain/boom length
becomes
moot.

This sounds like a place for the horn antenna similar to what we use
in microwave communications.

You have an interesting approach.

I am sure you have considered this, but how well do the multiple
reflectors work with the yagi? not so much those in line with the
elements as those that form a wall behind the driven element or the
first reflector.



If you look at current flow in a corner reflector antenna you will note
that rear elements individually carry little current! Food for thought
