Right now we are getting an extremely low bit rate, 400 bits/sec. We can't figure out why. The camera is about 50 feet away, the antenna is pointed at it. The signal strength on the modem is high, and the still camera right next to it is working well.
Any ideas?

The antenna may be too close, especially if indoors. Try to point the dish so it is not pointing right at the payload.

Is this the bit rate that is reported through the ubiquiti M5 modem webpage? If you type in the IP of the modem you can log in to the the modem using ubnt for the ID and password. Inside of that website you should be able to see the data rates through the modems.
Otherwise you can open a program on windows called resource monitor you can see what the network data rates for the wifi connection.

The issue that we have been dealing with is that the streaming bitrate to the ground station computer (to view the video stream in vlc and similar) is actually being throttled by our maximum internet upload speed. That is to say that we cannot view the stream on vlc on our local computer due to the fact that our upload speed is capped at 460 kilobits per second. If it would be at all possible to decouple the streaming to the website and the streaming to local host into two seperate processes or something similar (so that video may be directly recorded to the laptop), this may fix or amend the issue.
The issue that ffmpeg will not stream to the website remains as such even though ffmpeg is still attempting to upload data to the site. This compounds with the above issue.

payload --> flight ubiquiti --> ground station ubiquti --> ground station computer... is that your setup? then your local computer (ground station computer) should not be limited by anything other than the ubiquiti bit rate.
also with the ffmpeg command you can direct it to other feeds, however with your local network(school) limiting you then it would not help you.
ffmpeg -i rtsp://192.168.1.3:8554/ -c copy -f flv - | ffmpeg -f flv -i - -c copy -f rtp_mpegts rtp://localhost:4000 -c copy -f flv rtmp://media.stream.live:1935/live/[RTMPKEYHERE]
you can add another "-c copy -f ....." to push it to another location.
