Those frequencies need a waveguide interface. Even 11 does and they probably realize that was a mistake now. Doing a waveguide is no more expensive than a pair of 11 GHz N connectors. They could probably mold it out of plastic and have it metallized inside. I used plastic metallized waveguide in C band frequencies back in 1979.

I doubt they will do 18 and 23 GHz with N connectors. Even at 11 GHz, they are risking that people will just grab a standard coax jumper with connectors only rated to 6 GHz.

Guys, I know that there are features you all wish the AF11 would have like SFPs etc but I'm sure that would just raise the price on these things. I am very impressed by how far Ubiquiti has come from the last 10 years. What was their flagship product back then? XR5 and XR2 mini-PCI cards? And now they have full licensed links available that they designed from the ground up? As far as I can see if you compare Ubiquiti to the manufactures that have been in the licensed link business for decades they sure have introduced a lot more products in a shorter period of time. I am sure that AF11 is just the start of many more frequency bands that they will be doing licensed links in. (I can't wait for more bands) Personally for me the AF5X line has been a blessing. I have converted most of my backhauls over to them and the AF24 line is amazing as well. I couldn't be doing what I am doing today without these products, at least not without significantly raising my prices. Be thankful for what Ubiquiti has done for you.

Exalt kept promising auto xmt power along with ACM on their G2 radios, did they every deliver it? I heard frequency coordinators stopped coordinating links that way because it seemed to be a fictional feature.

I guess what you mean is that you engineered your link so that rain fade does not cause you issues. Yes, definately important to pay attention to your climate.

None of our 11 GHz links experience rain fade, but we don't have any longer than 10 miles. As for performance, I guess the final arbiter would be the number of bits/Hz. That is almost binary. So then you have to look at the bits/Hz/$? bp<part15sbs{at}gmail{dot}com> On 11/19/2016 8:27 AM, Chuck McCown wrote: I don’t expect rain fade at 11 GHz but I am in Utah. From: Ken Hohhof Sent: Saturday, November 19, 2016 9:17 AM To: [email protected] Subject: Re: [AFMUG] [WISPA Members] Who will have AF-11X First? Some random thoughts on AF-11x: 1) Traditionally a licensed backhaul vendor has been expected to have a complete line which for FCC means 6, 11, 18, 23 GHz. When Ubiquiti or Mimosa chooses to cherry pick 11 GHz, it’s like a convenience store that doesn’t carry everything you need to stock your refrigerator, just milk and bread. You will need 2 vendors unless you never have short or long links, or areas where you can’t coordinate an 11 GHz link. 2) I assume these are OFDM like the other AFx radios? It’s not obvious what performance advantages OFDM brings to this application, and it does add overhead for things like cyclic prefix and pilot tones, as well as latency and peak/avg ratio issues. It may have implementation advantages, but traditionally licensed radios have valued performance over everything else. 3) I have several AF-5x links and I like them, the software is kind of barebones though. I’m always surprised when I look for something in the stats or logs and find it isn’t monitored. You’d think software would be a strength for them. Mimosa seems more creative, and even a 10 year old Orthogon radio has more monitoring and troubleshooting tools. I guess software is something that can improve over time, although the AFx firmware doesn’t seem to get many updates. 4) With licensed links we are more likely to be putting them on commercial towers where we may be collocated with the big guys. Commercial tower owners are starting to insist on attention to low PIM (passive intermod). N connectors and coax jumpers would seem to invite PIM problems more than a slip-fit waveguide connection to the antenna. 5) RF performance of most licensed radios is per specs. Where the problems occur is often features like ACM, data buffers, etc. If you are using 11 GHz, you are probably expecting rain fades. How well has the vendor implemented adaptive coding and modulation, is it truly hitless, does it use the max xmt power at each modulation, etc. 6) Always pay close attention to xmt power at each modulation. The headline specs fors some radio may say 4096QAM and 26 dBm xmt power, but as you look at the detailed specs, the xmt power at 4096QAM may be 21 dBm, and you may not get that 26 dBm at anything over 64QAM. I would imagine this is especially important with an OFDM radio, since high modulation OFDM tends to have a high peak/avg ratio, requiring more headroom in the power amp. 7) The choice of coax connectors means you can easily extend the distance from radio to antenna, but you probably won’t due to coax loss. Most licensed radios have all sorts of adapter options for remote mounts and waveguide, which is more expensive than coax but higher performance.

I know of a company that already has 8 links deployed that they replaced existing radios with. They built their own radio core. (Second time for UBNT, if you count Invictus core and then this one... Not counting the ones they made before UBNT.) You underestimate them a lot. They're making more money across the board and investing even more money in R&D and labor than they ever have. The past few years they've made major internal changes, and things are just now starting to bare fruit from those decisions. They also have a huge cash reserve, and it wouldn't surprise me at all for them to start making acquisitions if they choose to.

HPx-11R, Remec round for Trango ApexPlus and HPx-11EX, for Exalt G2. Then we have Trango AD11G2-S2's and 3-S2's for ApexPlus, Remec round. So obviously we wouldn't be able to do the feedhorn swap on those. The RadioWaves 11EX are single-pol only, so those would need the feedhorn swapped. But the 11R is where it makes sense for the Remec adapter plate, especially in the case of the Trango dishes. So for me it would come down to $250-300? for the adapter plate vs $400? for a new RW feedhorn vs $1k for a whole new dish. This would probably be half as difficult if UBNT would've designed for waveguide, IMO.
