Only use low loss cables for cellular installations as the cable quality is as important as the antenna.Global Technology cables are designed to provide optimum performance.
Do not crimp or damage cable during installation.
Do not bend cable through an extreme radius.
Take care to tighten all fittings.
Waterproof any exposed connectors.
MIMO Technology
MIMO Technology utilises Multiple input and Multiple Output antennas to maximise the signal link and data carrying capacity of the wireless system.
Typically,WIFI(802.11n)2.4/5.8GHz systems or newer 4G LTE-A transceiver systems(eg, broadband wireless modems)have two antennas ports,and thus need a MIMO dual port antenna system to make use of this technology.
Should you use only on port, this will result in reduced data rates.
Global Technology recommends using our MIMO range of antennas where two antennas ports are provide. We can offer a range of both WIFI and 4G MIMO antennas to suit your application.
Mounting Tips
For better performance locate the antenna higher on the vehicle,or as high as possible in a fixed installation.Height always improved performance and range.
Do not mount antennas close to each other.Min distance should be 70cm between UHF/Cellular antennas.The further apart the two antennas,the better the performance of each respective antenna.
Do not mount antennas closer than 70cm to any metal vertical surface.
Antennas must be mounted vertically,this is particularly important with higher gain antennas.
Avoid affixing any object to the antennas as it could affect the performance of the communications system.
Do not mount antennas operation on the same band,at the same horizontal level unless a switch selects them.
Which Antenna Do I Need?
Gain Describes the shape of the radiation from an antenna.
Use a higher gain antenna for better performance in open flat terrain.
Use a lower gain antenna for better performance in rough mountainous terrain or city areas.
We recommend the use of a lower gain antenna for the communications in vehicle convoy situations.
Glass mount antennas are ideal for built up city areas where signal strength is higher.
High gain antennas are better suited for regional areas where long range is required.
Fixed site directional antennas send all the signal in on direction-they need to be rotated and/or titled until the strongest cell site signal is obtained during installation.
Fixed site OMNI directional antennas are idea when reasonable signal is available in the area.This is an easier installation option.
