Well, for those interested, I had to remap my whole yard. With the alt antennas I noticed what seemed like lag in the position detection. After the above suggestions I tried going back to the original antennas and, voila it started receiving signal again. After a little fiddling I found that the left hand antenna (looking from behind) only has about a 1/4 or 1/6 of a turn difference between being connected or not and being fully seated. i.e. fully seated and you get satellites. back it off just a hair and the satellites disappear. 
Another interesting thing, though I didn’t do much more testing to confirm, is that with the other antennas, while I was seeing more L2 and overall sats, for some reason my DOP never went below about 2.3-2.5, but with the original antennas I’ve gotten as low as 0.8-0.9.
With the remap, everything seems to be tracking now, but I still have the issue that the app can’t seem to connect to the Data Center. So I’ve put in a ticket for that. Also, now I’m seeing a thing where the robot seems to suddenly shut off for a few seconds and then come back on. It happened this afternoon when HAL 9000 got stuck and I had to move him remotely. I had my roommate go out and check on the rover. I had him on the phone and while I was moving it, it suddenly stopped responding and ALL the lights went out. Weirdly I was still getting camera feed. I went back to the map view and it suddenly showed the rover as no signal, no GPS, and then disconnected. I hit the link button after a few seconds and everything came back up and I could move it remotely again. This is not something I experienced at the end of the year last year when I was finally able to get HAL up and running and actually mowing, but I’ll keep looking into it and will make sure to keep track of the ticket.
