C.2 Internal Antenna Characteristics
Anybus Wireless Bridge II has 3 independent quarter wave monopole antennas. The following
radiation diagrams and tables show the characteristics of the different antennas as measured
under laboratory test conditions. The diagrams can be used as a general guide for finding the
optimal placement and orientation of the units.
The diagrams use a color spectrum from violet to red to indicate signal gain. The closer to the
red end of the spectrum, the stronger the signal.
