Ladderline behaves differently from coax, and there might be a small
impedance "bump" if you turn it abruptly through 90 degrees; however, in
many ladderline applications that wont matter. It certainly wont be an
issue if you are using the ladderline to feed a multiband doublet.
Unlike coax, a ladderline's RF field is not contained totally within the
cable, so you should keep it away from parallel conducting materials; a
safe distance is 3-4 times the ladderline wire separation.

Can 450 ohm ladder line be bent at 90 degrees around obstructions?
