Hello, i have been going around in circles trying to figure out why everytime i try to transfer a file over 2 Powerbeam 5ac 300 link it maxes out at around 290-300 Mbps when i had it going more than that before. (i don't know what i changed. Both Dishes are on software WA.V8.5.8-CS.38845.180918.1016 and are roughly 0.2 miles apart. I have attached screenshots of my settings. Any help is aprreciated.

You posted this in the UniFi section.
@UBNT-JaM could you move this to AirMAX?

It's accurate. Capacity by UBNT is both ways total. Thus, half of capcity is what you get one way (a little bit more in most cases). Also, you may want to reduce power a little to be in the low 50's, you may get the highest 8x modulation.

I say play around with it a little, start with each and look for the best results. Also, don't negate a well balanced chain link. Here is my reasoning for it when I was dealing with a 5x link:
Suggested Max TX Power:
8x 19-20 dBm
6x 21-22 dBm
4x 23-24 dBm
1-2x 26 dBm
1/4x 26 dBm
To be honest, I'm not sure if it applies to your link but something I've learned over the years, a signal TOO LOUD is not a good thing. Find the sweet spot.

The speed you get across the link depends very much on the type of traffic.
How are you testing?
Are you testing tcp or udp? How many streams?

As regards power then less is generally more. Thats a hefty link for such a small distance.
Try reducing power at both AP and Station a little.
Select a clear frequency manually, don't use Auto
