THE LEFT PICTURE SHOWS AN ANTENNA DIRECTLY UNDER THE CANOPY. THE ANTENNAS
RECEPTION IS VERY BAD.
IN THE RIGHT PICTURE THE ANTENNA IS POSITIONED LOWER BUT STILL HAS BAD RECEPTION
DUE TO BEING UNDER THE CANOPY.
QC1000 positions in the above drawings improve from left to right:
THE THIRD PICTURE SHOWS AN ACCEPTABLE POSITION. THE ANTENNA IS NOT COVERED BY
THE CANOPY AND IS AT LEAST 1M FROM ANY METAL STRUCTURE SUCH AS THE CANOPY, THE
HANDRAIL OR THE CABIN PLATFORM.
THE FOURTH PICTURE ON THE RIGHT EXTREME SHOWS THE ANTENNAS RECOMMENDED IDEAL
POSITION.
Antenna position with regard to the vehicle body in the top views:
THE LEFT PICTURE SHOWS HOW THE CANOPY SHIELDS A CONSIDERABLE PART OF THE GPS
AND RF.
THIS IS WHY THE RIGHT PICTURE IS HEXAGONS RECOMMENDED POSITION.
7.5 Tracked Vehicles
On tracked vehicles, the antenna must be mounted as close as possible to the axis of rotation.
For better accuracy, especially to sense a turning maneuver on the spot without losing heading, is
to apply the two-antenna configuration.
