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 80 cm. (from the ground
and the centre of the equipment). With medium sensitivity setting, the suggested crossing
overlap is at least 5 m., for CORAL-220S model and at least 3,5 m. for CORAL100S model
