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.
