This site is not ABAB. It's not even AB. It is merely A. One sector;
120° wide, with about 15 subs. About as low as you can go. The problem
is that most of the subs are near the outer edges of a 120° sector.
Dividing it into 2 sectors would be an option if we had (or expected)
more subs, but this one I don't think that will happen. I'm not inclined
to burn a Canopy AP (or two even) on 7 or 8 subs each.

I think asking for 3 dB down at 120 degrees in dual pol with matching
patterns, good F/B and good sidelobes is not going to happen. I’d plan
on ABAB and look for a 90 degree sector.
Hmmmm, the published patterns for the KPP “Gen III” are kind of ugly,
aren’t they? Plus the HPOL and VPOL azimuth patterns don’t match very
well.

I thought the KP sectors were suppose to be -3db at 120... I think
almost everything is rated at -6db now.

The new 120 is the old 90....search for something advertised as
wider than 120 I guess?
What I'm looking for is a 120° sector that drops off no more than
3db at the edges. The 6 db bull that seems to be common these
days is not what I'm looking for.
Also want good F/B ratio, good cross-pol performance, and tiny
side lobes. In perfect world, it would drop off 30db at 121°.
I want a pony too.

Good drop off is a good thing IMO.
If you want less drop off probably go with an original Airmax
sector. Those things bleed for days and the f/b isn't very
good. We installed half a dozen people 180* off one of them.

Has anyone found a decent TRUE 120° dual-polarity
sector in 5 GHz? We're using a KP on one of our
POPs and the drop-off at the edge of the 120° is
just too much for our taste.
