How A Portable Direction Finder Works

In a direction finder, there is an antenna or a loop antenna. The antenna is going to rotate to pinpoint the direction of the strongest radio signal. The strongest signal comes from the broadcasting station that the position is known already.

A navigator is going to use the directions as well as the radio stations to use the triangulation. Then the triangulation is going to determine the position of a target. However, the navigator must make the corrections in the readings from the direction finder.

The goal is to account for the radio transmission effect from the magnetic field of the target if the target is a craft.
