I was just going on your comment that it was barely enough for one TV.
If the cable company is the yardstick, they would rather install their amplifier than to have you put one in that might reflect noise back on their network. Cable quality might be more important than anything else at 200' out tho.
I would still try to work with their tech before I started buying stuff. He might have something that would get you going on his truck. This is a competitive market these days.
