I get the slant vs. h/v thing.
Interestingly enough my guys report that using the KP yagis with the KP
dual slant sector they can rotate the
yagis on the vertical axis to "fine tune" the signal...I.E. sometimes
30d slant.
Maybe vertical is the wrong word here...

Well, it'll work better than the Rockets...
The obvious differences between the UBNT and Cambium sectors are H/V
polarity vs dual slant, and 120 degree vs 90 (at -6db, the Cambium's
are sold as 65 degree, but I believe they are 90 at -6db). Not being
slant shouldn't be a problem in most cases, and the gain is about the
same. My biggest concern would be the F/B ratio, which doesn't seem to
be listed on the spec sheet for the UBNT antennas, but if you don't
need to do frequency re-use, that might not be too big of a deal.
We have one UBNT 900mhz sector, which we replaced with a Cambium
PMP450i (we actually added the PMP450i, the UBNT sector is still in
place, but currently powered off), and the signal levels stayed pretty
similar on the customers that we switched over for the most part (most
of the customers had Rockets with yagis). We plan to add a second
Canopy AP at some point, re-using the UBNT sector, and re-aim both
sectors to get more coverage, but hopefully we'll be able to switch
everything over to the UBNT sector for a bit (with the 450i AP on it)
while they're still both aimed the same and get a little better
comparison.

We have some sites with UBNT 900 sectors.
I wonder how the PMP 450i 900 would work in place of the Rockets
on the UBNT antennas?
Any opinions?
