The site and the intro video embedded does a good job explaining it, and I'm still learning the ropes here. But the main point is that there are inherent limitations of a patch array sector style antenna on its ability to maximize beam efficiency (basically how much RF energy goes out the main lobe vs what's lost to side/back lobes). The Array Sector antenna is built to maximize the beam efficiency to be the best possible. The gain is uniform across the whole spectrum, the V and H patterns are balanced which keeps your chain to chain performance even, and the back shield cuts out the lobes and makes for better colocation without the need for aftermarket shields. The build quality is great, and it's set up for all the standard slide and click radios like LTU, 3k, mimosa, etc. This makes for an optimized sector as best as you can get it.
While our primary focus is on the horn market, the array sector definitely has a place in a tools in the tool box approach. Typically these are used where clients are spread out across the coverage area, density is relatively low, and the distances are relatively long. Usually used in more rural deployments, but we're seeing folks mix them with horns in various layouts as well. We find that for LTU, the 60 degree asymmetric horn is typically the best fit for its mix of coverage area, gain, and noise isolation. Noise isolation is really important with LTU as that platform doesn't like noise at all, and typically a 90 degree pattern is too wide. You want a tighter coverage area with the best noise isolation that you can get, and the asymmetric horn fits that bill perfectly. Anyone looking for a deeper dive, please feel free to reach out and I can set up a chat with Tasos as he can explain this in deeper detail with more nuance than I can at the moment. We'll be in Dallas also. I'll be mainly handing out shirts and trying not to answer stuff wrong :-D On Thu, Apr 15, 2021 at 8:53 AM Mike Hammett <af...@ics-il.net> wrote: > What's so special about the new sector? > > > > ----- > Mike Hammett > Intelligent Computing Solutions <http://www.ics-il.com/> > <https://www.facebook.com/ICSIL> > <https://plus.google.com/+IntelligentComputingSolutionsDeKalb> > <https://www.linkedin.com/company/intelligent-computing-solutions> > <https://twitter.com/ICSIL> > Midwest Internet Exchange <http://www.midwest-ix.com/> > <https://www.facebook.com/mdwestix> > <https://www.linkedin.com/company/midwest-internet-exchange> > <https://twitter.com/mdwestix> > The Brothers WISP <http://www.thebrotherswisp.com/> > <https://www.facebook.com/thebrotherswisp> > > > <https://www.youtube.com/channel/UCXSdfxQv7SpoRQYNyLwntZg> > ------------------------------ > *From: *"Caleb Knauer" <cknauer.li...@gmail.com> > *To: *"AnimalFarm Microwave Users Group" <af@af.afmug.com> > *Sent: *Thursday, April 15, 2021 7:48:09 AM > *Subject: *Re: [AFMUG] Best 90degree Sector to use with UBNT LTU APs > > RF elements array sector is what you want if you want a 90-ish degree > sector. 3db drop is around 75 degrees, 6db is around 100 degrees. > Patterns on the site along with further info. > > https://rfelements.com/products/array-sector/array-sector-antennas/overview/ > > Lot of horn choices are available too depending on your deployment.
