Default UHF TV antenna theory

I built a 4 bay antenna for my daughter and it seems to work, I
received 21 channels at my home, which according to TVFOOL is about right.
But it got me looking at other antennas, I found a 2 bay fractal that
is simple, in that you just print the pdf, glue it to aluminum flashing
and cut it out.

So why not phase four together? What I see is some frequencies add and
some subtract. Also with a reflector, some frequencies add and some
subtract.
So I'm a bit confused, how does Channel master handle that on the
CM4228? Two phased 4 bays.

Opps, just found this need to read it.

Anyway looking for general discussion about combining 4 of the above
fractals, maybe optimized for channels below 50.

Instead of wondering and guessing, why don't you model the thing and then
know what will happen?
