Obtaining the Best GPS Quality

Placement of the GPS antenna is crucial to the quality of the data recorded by VBOX LapTimer. Any metal close to a

GPS antenna can disturb the signal in an unpredictable way due to interference from reflections of weak GPS signals.

For the best results, use the antenna in the centre of a metal roof at least 5 cm away from any metal objects such

as roof bars or radio antennas. Do not mount the antenna close to the edge of the roof as reflections from the ground

may interfere with the signals. Avoid the edges as reflections from the A-pillars will cause problems.

Mount the antenna as high up as possible and keep above any roll bars. Pieces of metal close to and above an antenna

will badly disrupt the GPS signal.
