8.8.4 Dual antenna mounting offsets
The easiest way to install the dual antennas is to place both antennas on the same longitudinal axis
at the same height. The primary GNSS antenna should be installed behind the second antenna with a
minimum distance of 50 cm to a maximum distance of 200 cm. Thus, no configuration of the offsets
between the Secondary GNSS Antenna to the Primary GNSS Antenna in the ADMA Webinterface is
necessary. Only the mounting offsets between Primary GNSS Antenna and ADMA must be defined.
In case of lateral or height offset between the antennas, the descending offsets must be configured
in XYZ axis via ADMA Webinterface.
It is important that both antennas are of the same type. Using two different types of
antenna may cause the solution to fail.
