If you just want to build a quad for the sake of building or owning
a quad, then great! But am I the only one would would wonder about
that choice if optimum station performance is the goal?
I know of no optimized quad designs that can compare with modern low
sidelobe yagi design. Why care? If you are way out in the country
with no neighbors and very well maintained power lines, maybe no
reason. Most of us don't have that luxury and must contend with a
virtual jungle of man made noise these days. A 6 meter antenna at
100 feet is going to hear every noise source around.
I am all for taking the road less travelled... to a point. I used
quads for many years on 2 meter EME. Later I used quagis. Those days
are gone. After a 10 year break I am getting back on 2 meters and
find that here in this mostly rural area outside a small town, noise
is up so much as to make those antennas useless for any serious 'DX'
work. I have built a yagi with well suppressed side and back lobes
in order to hear. My 6 meter situation is even worse and I really
need to ditch my old 7 element yagi in favor of something more
optimized in terms of pattern.
