2.5 Amplitude of the Sensitive Beam
The amplitude of the
Sensitive Beam depends
on the distance between the transmitter and the
receiver, on the
antenna type
and on the
sensitivity
adjustment set. The pictures below show
the diameter half-way of the sensitive beam section (based on the length of the section) in case
of maximum and minimum sensitivity (see next picture ).
