I would be concerned about 8 element quads.
I love quads. My first real antenna for 20-10 was a 2 element Cubex quad.
It worked great. I have used many wire quads on 40 meters and they also work
great.
However, I had a friend with a 6 element quad and it never really worked right
(it was on a 60 foot boom for 20 meters).
After I saw some modeling for them, I stated to see why. The two element quad
is a great antenna, but as you add more elements, it becomes less clear that
you are really getting much advantage.
Maybe someone smarter than me can explain why.
