External Antenna Position; Sector Antenna Solution - Delta DE212 Installation And Operation Manual

2.6 External antenna position

Figure 2.7 shows the position of the external 360° antenna behind the drivers cab.
This position gives reduced sensitivity at the front part of the vehicle but good
sensitivity behind the cab, where the operator normally is working.
In many cases the position of the external antenna can just be on top of the drivers
cabin, or even inside the drivers cabin close to the rear window.

2.7 Sector antenna solution

In some areas of the airport the disturbing signals can be extremely strong, and a
special antenna solution is needed. After several tests at different airports, Delta
can offer a solution that is easy to install and effectively reduces the disturbing
wireless signals and hence give the needed operational stability.
Sector antenna with installation bracket.
As shown at the photos, the sector antenna is installed at the working side of the
vehicle and is tilted about 20° down. This is important, when tilted down it will
normally not "see" the surrounding 4G base stations but will keep a good connection
with the fuelling operator at the tarmac.
