Long-line fishing, or long-lining is a fishing method that involves setting out a large number of short lines carrying hooks, which are attached to a longer main line at regular intervals. The short lines are suspended horizontally at a predetermined depth with the help of surface floats.

In a circuit with a “long” line, the line’s own characteristic impedance dominates circuit behavior.
