2.6 Length of Dead Zones near the equipment
The length of the Dead Zones near the equipment is based on the distance of the equipment
from ground, on the sensitivity set on the receiver and on the type of antenna used.
The suggested height, for standard installations, should be about 85 cm (85/90cm for
installation using special “butterfly” antenna). The height has to be considered from the
ground to the centre of the equipment.
With medium sensitivity settings, the suggested crossing overlap is about 5 m (3,5 if you
are using special “butterfly” antenna).

2.7 How to calculate the size of the beam and dead zones
In order to calculate theoretically the dimension of the microwave beam and the dead zones
generated with respect to the variable distance between TX and RX, CIAS has created a simple
application called
CIAS Volumeter available for free on our website:
www.cias.it
or on App Store to the following link:
