ANTENNAS
1. INTERNAL ANTENNAS
Ranger 4.0 contains celullar, WIFI, Bluetooth and GPS antennas.
Cellular, WIFI and Bluetooth antennas are capable of transmitting. Ranger should be
installed and operated with a minimum distance of 20 cm (8”) between the radiator
and the operator and the operator or any passengers.
The orientation and mounting location of Ranger4.0 can have an effect on
antenna performance.
To optimize GPS performance, mount the Ranger vertically with a clear view of the sky.
2. EXTERNAL ANTENNAS
If desired, external WIFI and/or GPS antennas can be used with Ranger 4.0
Specicantennaselectiondependsontheindividualsystemsetup.ContactTrapeze
for assistance in selecting an appropriate antenna.
To comply with FCC and Industry Canada rules, an external WIFI antenna must be a
monopole type with gain of no greater than 5dBi.
Use short lengths of low loss cabling whenever possible. WIFI performance is
especially susceptible to cable losses.
Some importance features to consider are:
Compact construction
Durability
Weatherproong
Temperature stability
Mode of Installation
Groundplane style antennas are ideally mounted on the centre of a metal vehicle roof.
Glass mount antennas should be mounted away from metal objects.
When using an adhesive antenna, it is extremely important to make sure that the
surface of the mounting location has been thoroughly cleaned. Use Isopropyl alcohol
to clean the surface just before securing the adhesive pad.
3. CABLE ROUTING
The antenna cabling has a minimum inside bend radius of 2”. Bending the cable
tighter will cause degradation in antenna performance.
Avoid routing the antenna cable in parallel with the vehicle wiring over long distances.
Do not coil excess antenna cable slack.
