There might be a u.fl connector inside for a GPS antenna, but I really don't know. There should be pictures on the FCCs website if you feel like digging. How many satellites does it see? Is there a large building outside the window where your magic box is? Anything significantly blocking the view of the horizon and sky? If so, is there a different spot you can move it?

Is there any way to connect an external GPS antenna? While my phone can get a good GPS lock, the MB Gold does not seem to be capable of doing so. I don't mind taking this thing apart if it is possible.
Writing this from a few miles west of Fredericksburg, where my phone defaults to 5 MHz of B2 unless I flat-out block that band. No idea why, as B2 performance is can't-run-a-speedtest poor here. B66 is fine, with something like 15x15 spread over a few channels, though upload speeds are poor. NR is hit-or-miss (mostly miss); I'm not seeing more than ~-110 RSRP on B71 so that cell site is apparently nowhere near here. Thing is, since that spectrum is so quiet, I can still pull 20-35 Mbps down on that band (10x10), though of course upload speeds are poor.
On the way here, I hit my highest-ever NR download speed: 201 Mbps, just north of where 290 WB merges into 281 for a bit. Uploads are low (~4 Mbps) and jitter was high, and I believe that was on 15 MHz of n71 plus >= 25 MHz of CA'd LTE (2+12+66 I think) but still impressive. I hit 179/22.7 right before.
Basically as soon as we hit the Belterra shopping area west of Austin, the network went from being capacity constrained to...not. NR wasn't available for most of the trip, but LTE turned in some solid speeds (70/10) on T-Mobile.
There was a point along the way where there was a near-complete dead zone...no Sprint, T-Mobile, or even AT&T roaming. I *might* have had 1x the entire time, but I think that even that dropped for about a half-mile. Sprint B26, then B25, were the first to come back, with T-Mobile B2 a mile or two later. If T-Mo put 600 wherever that Sprint site is on the west side of that dead zone, pretty sure there would be no more dead zone.
As an aside, B12 lower-A/B are owned by West Central Wireless near Fredericksburg, so T-Mobile doesn't have B12 here, only B71 and mid-and.
In contrast to T-Mobile's performance, Sprint had usable B41 most of the way, though there were points where my phone dipped to B25/26 if I didn't force 41. Actually got the fastest B41 download speeds I've seen on my phone around Deep Eddy, at 196/4 and 179/5. I think this was even on a MiniMacro rather than a full cell site.
Finally, yesterday east of Pflugerville (east of Lake Pflugerville) I hit 86.7/46.6 on 10 MHz of n71. Yes, some of that was CA, and yes, that's in a sweet spot where you're at the edge of urban cell spacing but are on a sector pointed out into the countryside, but I'll take it. By contrast, Sprint's MiniMacro had poor service there.
EDIT: Pretty sure I found the NR site SE of Fredericksburg. After setting my phone to 4+66+71+n71 I was seeing speeds topping out at 100 Mbps down, 15 Mbps up. Should've tried with NR disabled but didn't think to.
