Fig. 6.39: Radiation diagrams
Both antennas should be oriented towards each other using the peaks of the radiation diagram. Adjust
the antenna alternately in the horizontal and vertical axes and monitor the resulting signal strength.
Use the calculation of the expected RSS with the precision of several dBm as guidance. Side lobes
transmit a signal ca 20 dBm weaker, see the Microwave link Calculation
