The radiation diagram is shown for horizontal alignment and for a center frequency of 915
MHz.
The radiating/receiving angle of the antenna is defined by the angle between the two -3 dB
points (corresponding to half the power referred to the maximum performance at a 0° angle).
The optimum radiating/receiving angle is therefore approximately ±35 degrees.
