Now that all the opinions are out there…. The post from Daniel Sullivan, that he just confirmed on the list applies to 5 Ghz and 2.4 Ghz was this… exact quote…”In tests we have undertook, there is no difference between slant and H and V with regards to MIMO-A and MIMO-B performance.”
Thanks for the clarification Dan ! ☺ From: Af [mailto:af-boun...@afmug.com] On Behalf Of Jon Langeler Sent: Friday, December 04, 2015 3:23 PM To: af@afmug.com Subject: Re: [AFMUG] to slant, or not to slant - that is the question That would only work if the radio is capable of signal combining or MImo-A and also halves your throughput.

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.

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… Sincerely, Joshaven Potter MTCNA, MTCRE, MTCWE, MTCTCE, UACA Google Hangouts: yourt...@gmail.com<mailto:yourt...@gmail.com> Cell & SMS: 1-517-607-9370 supp...@joshaven.com<mailto:supp...@joshaven.com> On Dec 4, 2015, at 1:59 PM, Paul McCall <pa...@pdmnet.net<mailto:pa...@pdmnet.net>> wrote: 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. Paul
