You still have to do the divide by how many arms to the power divider
cabling, as someone mentioned it weakens the overall rx department,
however I have tryed this with just 3 3 element beams using the tower as
the reflector and it seems to work pretty good, when the weather is a
sure thing we are gonna try 3 more 40 feet below the first batch and see
what develops. I think with the larger beams you are asking for some
wind shear that could ruin your handiwork, if isolation into one area is
imperative try making a corner reflector with 1/2 inch or larger
hardware cloth covering the reflector frame or make a double tri-ghonal
reflector as described in the arrl antenna handbook as a single - you
will experience about 4.0 to 4.5 more forward gain without adding a
large lever out front for the wind to get into - this would be in
exchange for the corner reflector project.
