Step 3: GPS/GSM Antenna
The AT-V4 Pro uses an internal antenna for both GPS and GSM
(cellular) signals. The GPS and GSM antennas are located
opposite the cables when viewing unit from the top or bottom.
(Reference image C.)
Our device transmits once every 30 minutes if sitting still, or
once every 5 or 10 seconds (depending on your rate plan) when
the vehicle is moving faster than 4 mph. Driving the vehicle
around the block will assist in its first data transmission.
The best location is under the dash, above the instrument
cluster with a full view of the sky through the front
windshield. (Reference image D.)
Make sure the device is kept free from direct
exposure to the elements (sun, heat, rain, moisture).
When installed inside a building, your unit may not
receive a GPS signal or cellular signal.
GPS signals WILL penetrate glass, plastic, foam,
fiberglass, and wood.
GPS signals will NOT penetrate metal.
A good placement of the device will yield a
minimum of 7 satellites.
The device will not transmit data location with
less than 4 satellites in view.
