make sure that there are no dust particles in either connector. Replacement antennas are available by contacting your
VBOX distributor.
The antenna is a magnetic mounting type for quick and simple mounting to the vehicle roof. For optimum GPS signal
reception, make sure that the antenna is fitted to the highest point of the vehicle away from any obstructions that may
block satellite reception. The GPS antenna works best with a metal ground plane underneath (eg. Vehicle roof).
Please also note that when using any GPS equipment, a clear sky view is important. Objects in the surrounding area
such as tall buildings or trees can block the GPS signal causing a reduction in the number of satellites being tracked or
introducing reflected signals that can decrease the accuracy of the system.
GPS antennas require a ground plane to operate correctly. Usually, the metal roof of a vehicle performs this function.
However, if a test requires an antenna to be placed off of the vehicle, you need to use a special ‘mushroom-style’
antenna. These antennas are capable of operating without an additional ground plane as they have an internal one. The
Ground Plane Mushroom-style Antennas (RLVBACS065) are available from your VBOX distributor.
