Remember, AF is not WiFi based. They are constantly working with their design to get the cleanest signals, highest throughout, etc.
Think of the UBNT Chicago team as a cabal of Mad Microwave Scientists all sitting around that FPGA while grinning and wringing their hands together.
Every couple of days or weeks they sacrifice enough hardware to the RF gods that they figure out a new way to get more performance out of an existing product or think up a new one ;)
According to the certification, it’s 28dB in the upper band

The AF5X was just submitted in January. It is certified under the new rules.

With a 34dBi antenna you would actually have to be running at -4dBm in UNII-2, so that would be more like -67.
If I'm reading that FCC cert. right, it looks like they're able to do something like 27dBm in 5.8ghz... why are they able to do higher power than in UNII-1? Were they still able to get it certified under the old rules? Mimosa stuff is stuck with the same 17dbm in UNII-3 as it is in UNII-1, since they're only certified under the new rules.

Thanks,
Planning a 11.2 mile link with 34dB antennas in UNII-1
I get the following theoretical levels:
UNII-1: 17dB ~Rx -43dB (right at the recommended max – probably would turn it down)
UNII-2: 5dB ~Rx -58dB
UNII-3: 27dB ~Rx -36db (obviously too hot – would turn down)
With 75% duty cycle we should see roughly 375/125 although I’d take 80% of that.

You can reach 48db with a 3’ dish

Thanks,
This statement from Wikipedia made me pause…
200 watts (+53 dBm) point-to-point. [1] However, strict out-of-band emission rules limit practical point-to-point power to lower levels.
I can work with 17dB

Sorry, 17 db.. Miscalculated by a decimal point

Anyone know what the AF5X max Tx power is for the UNII-1 band?
My understanding is that in PTP the rules are the same as for 5.7-5.8.
