Installation
GPS Receiver
The enclosure is made from 6061 Aluminum alloy. It should be
mounted in a safe location, away from electrical noise, vibration and
temperature. Maximum operating temperature is 70°C or 158°F.
NOTE: To counter any possible vibration damage, please mount
the receiver box on soft Velcro, not the hard industrial type or
even double sided foam tape.
Antenna
The location of the antenna is VERY important. It should be
mounted such that it can have a clear view of the sky out to 5 degrees
above the horizon. Poor mounting locations will have a large negative
impact on the results from its calculated data.
Normally the best location would be on top of the race car. For
motorcycles, on top of the rear fairing works well. On a closed-wheel
race car the best choice is the roof. For best performance, do not place
the antenna under the front or rear window. For open-wheeled cars, on
top of the roll hoop, or just in front of the cockpit works best.
It’s best to have the correct length specified when ordering.
•
GPS signals are easily blocked by electrical noise. Keep the
antenna more than 6” from any other antennas such as car-to-
pit voice radios, telemetry and other GPS antennas.
•
For cars with “live TV coverage cameras”, most of them send
their signal at the same frequency as GPS. Therefore you
must separate the GPS antenna and wire to the opposite side
of the car. Keep the TV antenna and wire as far away as
possible from the GPS antenna and wire.
•
Keep the antenna outside any of any metal or carbon fiber
enclosed space, as these materials will block satellite signals.
Plastic, duct tape as well as fabric convertible tops are
generally ok.
•
The antenna should be kept flat or parallel to the ground. If
mounted on a slope then the ability to receive signals will
