I have heard some things, can’t really betray a confidence but schadenfreude may have been my emotion.

Then again, I have been trying to get two of their dual frequency sectors which are supposedly out of development since WISPAPALOOZA in October. They were "two weeks out on the shipment" two months ago. Then it was "should be here by XMAS". I called again this week and was told that there would be a sales meeting next Thursday and maybe then they would know something. I think the boat sank. My last two orders from KP have been nothing but issues. Since they had some new products I figured I'd try them again. Not super impressed.

If you really want a 120 degree sector there are some dual slants out there (L-com has one), but all of them I've seen seem to have fairly poor F/B specs. Also, I heard Cambium does have a 120 in the works... whether or not that's still going to happen, I don't know.

Plus there is no F/B spec. If you already have one on the tower, it makes sense to try and use it. But for a new installation, is the difference between 90 and 109 degrees enough to worry about? Or maybe ring up KPP and see if they have something in the pipeline that would be 120 degrees at 3 dB, dual slant, good F/B, and maybe even with N connectors and a mounting bracket for the 450i AP?

I spent about 2 weeks in denial before I finally gave up. Maybe someone else here will comment on possibilities.

We tried every possible combination even slant holding stinger on a 45deg angle. I was just hoping to hear from someone who could explain why or perhaps from someone who got it working.

I'm a little concerned about using V/H as well, which is why I opted to go with a Cambium sector for our first AP, rather than doing this project now. Apparently it does work to mix V/H and slant antennas with PMP450 - Cambium confirmed that is the case with 3.65 (the new high gain SM is V/H and the sectors are slant), so I'm assuming it will work fine with the 900mhz 450i as well... and the Cambium dual slant yagis can easily be converted to V/H as well... whether or not it will work as well as slant, probably largely depends on the environment it's deployed in.

We haven’t implemented 450i-900 yet but would be concerned about V/H vs Dual Slant.

If there are multiple sectors on a tower, you may run into some issues doing frequency re-use, since I don't think the F/B ratio is as good as the Cambium sectors, but if you're talking about a single sector, I don't see that there would be any issues. I am actually planning to upgrade the Ubiquiti 900mhz sector we have to a 450i this spring, and re-use the UBNT antenna.

Ubiquiti 120 Degree 900MHz MIMO 13dBi (AM-9M13-120) Would it work with either a pair of PMP100 AP’s to provide v/h coverage or with the new 450 gear in a V/H implementation? Thanks, Steve
