Antenna
•
GPS signals are easily blocked by electrical noise, especially in
the 1.5 to 1.6GHz range where GPS signals are transmitted.
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
decrease slightly. Keep this in mind when mounting on a
motorcycle as the bike leans from corner to corner.
•
Try to keep the antenna mounted on the centerline of the
vehicle. As with normal wheel speeds, during cornering the
speed of the inner side of the chassis is less than the speed of
the outer side of the chassis.
•
The antenna has a magnet base to hold itself onto a metal
surface. If you use double sided tape or hook & loop, when
removing please be careful not to remove the bottom silver
sticker from the antenna. This sticker has a metal film that help
reject false signals and shield it from noise.
•
Any extra antenna wire can be zip tied in a back and forth
bundle.
Do not coil the extra antenna wire length in a circle
or wrap it around anything. Simply run the extra antenna wire
back and forth.
