The DSP in the ePMP can do some kind of processing to correct for the 45
degree offset when you have slant on one end and V+H on the other. I
might not be stating it with the correct technical jargon, but that's
the gist of it. They sell a dual slant sector for the AP with the
intent to use it with V+H integrated SM.
This is a built in feature of the Atheros chipset, so presumably UBNT
radios can do the same thing.
That all said...I would try to match them up as just a matter of principle.

Your AP & SM should always have the same antenna orientation. I
promise you that you don’t want slant on the AP and not on the CPE.
If the signal is so obstructed that the orientation is screwed up to
the point that unmatched polarization is actually a benefit then there
is something seriously wrong…

We are looking at smaller sector sizes for a 5 Ghz ePMP cluster (60
degree probably), and am considering my options, which might also
increase my gain quite a bit. Using a non-Dual Slant sector such as
AM-5AC21-60, would increase my options. There have been a calling
threads on Cambium’s sites about whether Dual Slant was a big factor
at the AP if the SMs aren’t dual-slant.
Cambium’s Daniel Sullivan made this comment … The thread was
originally about 2.4 Ghz options, so not sure if it applies exactly
to 5 Ghz.
