Hi Steve - Happy to see Aruna is working out for you! I feel like such a caveman with my collection of antiques 
Currently running the BR1 mini LTEA with an older AP1-RUG (the olde one with three antennas) and a Mobility 22. This setup worked a charm last year from the Bahamas through Penobscot Bay with only a few gaps up in Maine. Speeds were more than adequate for us - but we’re not working on board!
I’m building an upgrade this winter whilst hanging around in FL getting two new knees (never get old - it isn’t any fun) with a BR1 Pro Cat20 (paid thru 6/27!) and a Mobility 42, as it has the requisite 4X4 cell antennas and also better performance on Band 71, which would have helped Down East. I’m also changing the installation to cut out about 10 feet of coax - the extra coax & connectors can’t be helping much.
On the olde AP1 RUG, I’ve tried to spread the coverage around the boat by running the antennas out - the AP is at the Nav station in the salon, I wired one back aft in the stateroom (nameless Chinese puck) and one up top on the coachroof (MobileMark) at the front of the cockpit. Seems to work, but I haven’t really explored to see how far off the boat it gets. One question I could never get answered was whether all three antennas are dual-band, or if Peplink split them up.
