Polar Plots
This diagram shows the strength of the signal received by the whip antenna on both
a horizontal and vertical plane. The diagram shows the magnetic field when the
antenna is in a vertical position. The red solid line represents the horizontal plan
and the green dotted line represents the vertical plane. You can see in the
illustration that at 90 degrees, the signal strength is 0 (as expected).
