Chapter 3: Installation

Installation
placed inside the radar beam, configure the radar to have a blanking zone to avoid
transmission towards the antenna.
GPS receivers
Good quality GPS receivers work properly very close to the ADU - typically down to one
meter outside the main beam.
Other transmitters
See the following figure for minimum recommended distance to transmitters in the
frequency range below 1000 MHz.
CAUTION!
The ADU must never be installed
closer to a radar than “d min.” - even if
experiments show that interference free
operation can be obtained at shorter distances
than “d min.” in the previous section.

1000 MHz
