Thanks for the clarification Fred. When I originally read Cameron's post, I did not see what he wrote below it about "But you can build two yagis ..."

No. The OSCAR circular-polarized antennas had a feed split between the V and H antennas, which each had a driven element. The MIMO ones have independent feeds. Scottie Arnett President Info-Ed, Inc.

Typically this was done for circular polarization (one feed, phased to give the right chirality), and used on the OSCAR satellites.

I have heard that the AP sectors Ubiquiti has released are not correct comparable to most sectors due to some -3dB down stuff. Like the 120 degree sectors are more like 90 degree? Is this true? is it true for all unlicensed bands? In my situation, I would really like to see a dual polarized 900 Mhz yagi, if it is even possible. We have many hills in our area, and we are trying to get more bandwidth to our customers. We have been/are using Canopy, but have some test units setup to try Ubiquiti for more bandwidth. Many consumers do not like the dish/loco Ubiquiti has, and we tried the panels from ITElite and most are not satisfied with the aesthetics of them also. Scottie Arnett President Info-Ed, Inc.

I'd vote for the 90s, but we aren't likely to use anything other than 120s in the near future anyway. From: [email protected] [mailto:[email protected]] On Behalf Of Shane MacDonald Sent: Wednesday, November 02, 2011 9:59 AM To: WISPA General List Subject: [WISPA] UBNT sectors 120s, 90s, or 60s? We are trying to decide which degree Ubiquiti sectors to release in December. Our production line can handle two of the three for a mid December release date and want your feedback. The 120 degree version is pretty much a lock but we want your opinion between the 90s or 60s so we release the sectors you require. Please reply to the list or send me an email directly as your response will weigh heavily on our decision.
