 First, protect the RF cable in a braided sleeve for the whole length of the coaxial cable, from
the antenna to the CAS unit.
 Use zip-ties at the beginning and the end of the cable to tie the braided sleeve to the coaxial
cable
 Do not cut the left-over of the zip tie to ensure the coaxial cable does not move freely inside
conduit.
 Insert the coaxial cable protected with the braided sleeve into the cable conduit.
 Attach the cable conduit mechanically to the nearest possible structure: antenna bracket,
antenna pole, hand rail or chassis.
 The free, unattached length of the conduit should be 15cm long, but never longer than 30cm.
 Respect the bending radiuses for coaxial cabling!
Remember to follow the water-proofing rules described above before installing the sleeve and
the conduit.
4.4.7. Through-Hole Mount Antennas (QF012, QF020, QF036)
The through-hole mount antennas are the recommended antennas for permanent installations due to
their strong mechanical attachment to the vehicle. The following section describes the general
recommendations for installation procedures specific to this type of antennas.
The through-hole mount antennas have the following properties:
 A threaded metal shaft, which receives a ¾” – 20 threads nut.
 The shaft is hollow giving path to the pigtail of 2 or 3 approx. 10-15cm long coaxial cables.
 The cables are confectioned with standard male SMA connector for GPS and RF signal
cables and a reversed male SMA for the WiFi signal cable.
 The shaft thread is ¾” with 20 threads per inch and is ½” long. The through-hole mount
antennas are shipped with the matching ¾” Nut and a isolating nylon washer.
 The attached gasket provides a sealant to prevent moisture from entering through the
mounting hole.
Do not use the triple antenna (QF036) for GPS, RF and GSM since RF and GSM signals will
interfere and render the system non-operational. Instead use a combination of GPS+RF antenna
(QF012) on the roof with a separate adhesive GSM/LTE antenna (QF034) in the cabin.
In order to mount the through-hole antenna the following operations must be performed:
 The antenna requires to be mounted on a horizontal metal surface which is in diameter 1-
2cm larger than the diameter of the antenna. Any metallic surface larger than this is
acceptable.
 If no such surface can be provided, mount an extra surface at least XXcm wide as mounting
surface.
 A hole must be drilled or punched into the surface. The diameter of the hole must be at least
22mm (0.866") in order to fit the antenna and the compulsory insulating washer.
 The surface should also not be thicker than 12mm (1/2") in order for the threaded shaft to
protrude through the mounting surface.
