I don’t know much about electronics, so any advice would help.

I’m also interested in knowing realistically what the upper limits are for this sort of thing.

      I agree with this. And also, if the highest range is your goal, you’ll want a directional (not omni-directional) antenna. Even a cantenna might be good for your use case.
