 Avoid placing the antenna close to the ground or having it point downwards – instead
face the antenna horizontally or point it up into the vehicle if the ground clearance is less
than 1.5 ft (46 cm).
Antenna Cable Routing
DO:
 Choose the proper cable length for the given antenna location.
 Protect the cable from heat and sharp edges e.g. keep adequate distance from exhaust
pipes and avoid potential chafing on sharp metal.
 Route the cable along existing cable tree on the underside of vehicle (i.e. along I-beams
for tractor trailer).
 Provide some slack in the cable (a few feet depending on vehicle application) at each
end point of cable / antenna to allow for slight repositioning if needed.
 Route “head first” for hole-through & magnetic mount antennas when passing cable
through frame holes and tight access points (route small cable end first always).
 Apply cable ties every 2 feet (61 cm) to ensure secure attachment – avoid chafing by not
over tightening.
 Secure antenna cable with cable ties on both sides of the connectors for extensions,
splitters and antenna mounts.
 Make sure all connections are properly locked and secured.
 For TNC Hex heads, apply 17 to 23 inch-pounds of torque.
DO NOT:
 Do not strain the cable and its connectors if length barely reaches – choose a longer
cable (chassis-flex during driving may tear an already tight cable).
 Do not subject the cable to sharp bends – try to allow for a natural cable path flow.
 Do not route over or under moving parts like steering linkages and shock mounts.
 Do not over-tighten cable ties.
Receiver Placement
 For outside mounting, Wireless Gateway Receiver must be properly secured via bolt-on
faceplate, heavy duty straps, or custom mount.
 Mount the Wireless Gateway Receiver ‘away’ from forward driving direction e.g. if
possible, have object between receiver box and open road surface such as a cross
member.
 Preferred mounting orientation to shed water is vertical (Connector side facing down).
 Apply the same precautions described under “Antenna Placement” since Wireless
Gateway Receiver has built-in antenna.
Caution: Make sure all power input lines are fitted with 5
Amp fuses for proper protection of the SmarTire
™
system
components. If the Gateway Receiver, Gauge, and
Diagnostics port are hooked to the same power line, only
one 5 Amp fuse is required before the line branches to
each part.
