5G Router/Antenna recommendations?

I live on a farm in the UK. Mobile broadband is really the only option I have and 4G just isn't fast enough for my needs (Working from home and have a job that involves a large amount of data transfer).

I've been trying to look for a 5G solution to the problem but I'm starting to feel like I'm jumping the gun. There's so little information and so little choice. Just wondering if there's anyone here who could give me more of an idea of what I should be looking for, what I need, and if I should even be doing this.
