99% uptime completely own powered. no need to connect to any power lines. remove snap to grid if you don't want it.
one radar needs 7 hours 20 minutes to fully reveal max area.
four of these blueprints rotated and placed in same chunk will fully reveal in 2 hours. active view: 7x7 chunks full view: 29x29 chunks. or 14 in each direction not counting the chunk the radar is in.
if you fill inventory with 2 stacks of solar and 2 stacks of accumulators and one stack of everything else you will be able to place 12 of them. So go into a car and drive around your base far out and and place them completely non connected to anything.
