Slow upload speed and T Mobile home Internet

I have been sent 3 different modems in an attempt to fix issues. I currently use the g4se, which has an easier interface with my MIMO 4x4 external antenna, which is pointed directly at my nearest tower, with a much better signal tower on the far side of that tower. I regularly clock 200+ mbps download, but rarely get above 2 mbps upload. Waveform, the company I bought the antenna from, has been far more thorough about attempting to resolve the connectivity issue than most everyone I've talked to at T-M (the tech guy Greg being the exception, thanks Greg). The last time I spoke with Greg, they had put in a ticket to get the tower slightly adjusted to provide more direct coverage, but I'm assuming the tower people said "No" as I've not heard back about that. It is worth noting that I do live in the "country" and there are plenty of trees around. My next attempt will be moving a pre-existing satellite dish tower to a better location in the yard and crossing my fingers.
