Dost lipnu na tych slant antenach...tak pravdepodone to musia mat overene, ze to je o dost lepsie:
ubnt-salvador: Hi guys,
It's true that it can be adapted by DIYers. However, we don't officially support it, and it's not possible to slant polarize that antenna, cause the AF-5G-OMT-S45 isn't compatible with RocketDish 5AC-31dBi antenna. So, in most cases it's not recommended to use AF5X with RocketDish 5AC-31dBi, unless RF spectrum in your area is very clean.
taktiez zaujimava myslienka od UBNT-RObert (neviem ci Pera...):
The reason we didn't highlight it for use with AirFiberX is because it is not 45deg H/V slant capable. We want to encourage the Industry to deploy multipoint (AirMax) on V/H pol and point-to-point (AirFiber) on 45deg slant pol to provide additional PTP/mulitpoint isolation and improve overall network performance.
V preklade: chcu na spoje slant anteny a na ptm v/h klasika....
There are only two orthogonal basis functions. That is, there are only two things that are completely isolated in RF (without multipath).
H/V are (ideally completely) isolated from eachother
±45° are (ideally completely) isolated from eachother
RHCP/LHCP (ideally completely) isolated from eachother
Any two signals that are 90° separated are ideally isolated.
The best you can get from everything else is 3dB. But, 3dB matters. That's what they're going with here. Use ±45° for backhaul, H/V for PTMP. That way, you get 3dB extra isolation between your backhaul and your PTMP.
H/V is isolated from ±45° by 3dB.
H/V is isolated from RHCP/LHCP by 3dB.
±45° is isolated from RHCP/LHCP by 3dB, and so on.
