On the other hand the antenna should be close to the center of rotation of the vehicle type to
make the positioning error due to the rotation of the vehicle as small as possible (see Figure
24).
The position of the antenna(s) is in some cases a trade-off between minimizing the error due
to construction barrier on the vehicle and the minimizing the rotation error. Contact Symeo if
there are questions regarding the installation position of the antenna.
If a second antenna is used on the vehicle the distance to the first antenna should be at least
1 meter to calculate an orientation of the vehicle. The orientation is necessary to determine a
load position if the antenna is not mounted above the load position.

Depending on the position of the LPR-2DB Integral Stations different minimum system
ranges result. The system range depends on the selection of the antennas and the antenna
cable length as well as of the antenna cable length. In general the antenna cable length on
the vehicle should be as short as possible to minimize the signal loss in the cable.
