Yes. Airfiber doesn’t have frequency lists, the frequency and channel width must match between ends.
I’m operating on the theory that I have SMA connectors on the antenna and coax jumpers trying to have lesbian sex. I actually ordered the SMA version of the panels by mistake, in the past I’ve ordered them with N connectors and didn’t realize there was another model number. But those were for 450 SMs which have N connectors, and these were for airFibers which have SMA connectors, so I decided it was for the best. Unfortunately I didn’t check the connectors to see if they RPSMA, I just assumed. This would explain why airView picked up almost nothing. (When will 7.x firmware come to airFiber, weren’t we promised Java-free airView? Using Java for this is awful in so many ways.)

It's actually fairly common for SMA connectors on antennas to not be reverse polarity.

Good thought, I had frame length at “default”, I changed it to 2 ms both ends, still nothing. So it could be bad radios, bad coax, bad antennas. I used the Mikrotik blue jumpers which I’ve used before with no problems, it was a new shipment I’ve used the Mars panels before, this time got them with SMA connectors (actually turned out to be right angle which I hate), in the past have used N connector model. The spec sheet doesn’t specifically say RP-SMA, of course now they’re on towers so I can’t look. What do you want to bet I’ve got male and female threaded connectors both with male pins? I just assume SMA connectors are always reverse polarity.

The only thing that comes to mind that's any different than the AF-5X is that you need to make sure the frame length is set the same on both ends of the link. I'm assuming that it would show something on the main tab if it was an LBT thing... the AF-5X says something like "radar detected" in red, so it's pretty obvious... I'm assuming they do something similar, but I've never seen it happen. As long as all of the settings match on both radios, it ought to work. I know the 5X's don't care which connector is plugged into which polarity, so I'd be pretty surprised if there was something like that going on.

Today we replaced a Powerbridge 3.65 link with AF-3X and it just won’t work. Master says beaconing, slave says syncing. Is there some trick to these other than the obvious bad radio, antenna or jumper? It’s on the same channel as the Powerbridges which had great RF performance, so it shouldn’t be an RF path problem. The only thing I did nonstandard was I decided to mount the antennas (Mars panels) as V-H instead of dual slant. I don’t need to swap V and H at one end or something weird like that, do I? I looked for any config items I might have wrong, there’s not much. Ubiquiti’s LBT implementation doesn’t seem to have alternate frequencies. I’m not sure what it would say if it was not transmitting because of LBT.
