WiFi Car Antenna installation
Antenna mounting position
•
The antenna must be mounted as high as possible on the vehicle.
•
The mounting position must give clear line of sight between the vehicle antenna & the pit
lane antenna when the vehicle is travelling in the pit lane.
•
The surface to which the antenna is attached should be flat. A maximum contour of 12mm
(0.5”) is allowed within a diameter of 0.2m (8”).
•
The mounting surface should be horizontal to /- 10deg max.
•
The antenna should be adjusted to keep the antenna /- 5deg of vertical.
•
No structural material or bodywork, should be higher than 25mm (1”) within 0.6m (2ft)
radius of the antenna base.
•
The antenna must be mounted so that the connecting cable to the STACK module is 3m
(10ft) or less.
•
The connecting cable to the STACK module must be kept away from water ingress.
•
Minimum distances to any other radio or telemetry antenna must be greater than 0.5m.
(18”)
Antenna Fixing Instructions.
The Antenna mount is suited for panel / roof mounting. The Antenna requires a minimum
90mm (3.5”) diameter metal ground plane to be fixed under the antenna. If the fixing panel is
non metallic then a metal disk of the required diameter must be fitted under the panel.
Installation can be done in an 18mm (0.71”) dia. hole with access from the outside only if
required.
The Whip antenna should be tightened with a 9mm fork spanner.
The mount has a bendable section (+/- 15deg) to adjust the antenna into an upright position.
The antenna cable must be routed from the antenna to the Monitor module as follows:
•
Minimum allowed bend radius is 30mm. (1.25”)
•
Take care not to over tighten any cable ties such that they deform (pinch) the cable.
•
Should be secured in such a way as to stop mating connectors from being pulled apart.
•
Such that it will not be trapped or crushed by any other item on the vehicle.
•
It is essential to ensure that the Monitoring System and harnesses are
NOT
mounted in a
position which is close to any devices, or associated wiring, similar to the following:
Suggested Wiring Clearances
Min Clearance
Ignition HT & coil leads
75mm (3”)
Radio transmitters
50mm (2”)
Fast switching inductive loads like fuel injectors,
hydraulic solenoids.
50mm (2”)
Any powerful source of heat
Shield with reflective material
