I was flying my Mavic 3E about 2000 feet away at around 325 feet around some new construction sites. There were no obstructions between me and the drone and twice when I was at a particular angle to the metal buildings, I got a "controller signal blocked" which resolved as soon as I moved. I could still see where the drone was in the sky.
Then I got a "collision warning" even though there was nothing at my altitude - not even birds - and the number of satellites dropped to zero. After moving again, the satellites picked right back up.
I brought the drone back to inspect it and saw nothing wrong so I'm assuming some kind of RFI. I flew back to the spot again and was able to repeat the issue. One possible issue is a cell/antenna tower about 500 feet away - but I've flown much closer and all around this tower in the past without issue. However, the factory I was over does a lot of welding - perhaps that might be an issue? In the 2nd flight, I tried flying through the area again and then flew past it to see if I ran into range issues which didn't appear to be a problem.
Is it possible I flew into the path of a microwave beam from the tower and that affected the drone signals?
