CORAL-PLUS
2.2 Number of Sections
Before the installation, we have to think about how to install the system.
Therefore,
remember that it‟s always preferable to install an even number of section. This
because in a close perimeter which is
made of an odd number of sections it‟s present one
corner where there are one Transmitter and one Receiver which can produce an interference
between themselves.
In figure 1a the angle between the two heads Tx and Rx is correct, but the two heads are too
closed one to the other, and the Transmitter in front to this Rx head is too far, so the spurious
signal coming from the close transmitter may be high compared to the its own.
In fig 1c the angle between the two heads Tx and Rx is more than 90° and this is wrong. In
addition these two heads are too close one to the other.

2.3 Ground conditions
It is not recommended to install the unit along sections where are present high grass
(higher than 10 cm), ponds, longitudinal waterways and all those types of grounds which
its conformation is rapidly changeable.
