2.4 Presence of Obstacles
The
fences
, are generally
metallic
therefore highly reflective. For this reason some precautions
are suggested:
- Make sure that the fence has been properly
fixed
in order to avoid wind movements
-
when it‟s possible the microwave beam shouldn‟t be installed in
parallel
to a metallic
fence
but with an offset between the two heads of 2 m. (pic. 2)
- if
it‟s necessary to install the microwave barrier between two fences, make sure that the
distance
between those two isn‟t less than 5 m. In this situation it is recommended to not
use the barriers for more than half their maximum range.
-
Trees, hedges, bushes in general
, need
very great attention
if
they‟re near or within
the protection beams. These obstacles may vary in size and position, in fact they grow
and they can be moved by the wind.
Figure 2
It‟s possible to tolerate the presence of these elements near the protection sections only if their
growth is limited through routine maintenance.
Inside the bundle of protection, it is also tolerable the presence of pipes, lighting poles and
other similar obstacles taking into account their size cause it may
be the
cause of
Dead zones
not protected and
Hypersensitive zones
which cause false alarm.
2.5 Amplitude of the Sensitive Beam
The amplitude of the
Sensitive Beam depends
on the distance between the transmitter and
the receiver, on the
antenna type
and on the
sensitivity
adjustment set.
Note:
In cases where you need a larger the beam on the vertical plane, you can use the
optional accessory antenna "Butterfly" cod. PAR-BF
.
WARNING!
For installation on concrete or asphalt with distances longer than 50m the "butterfly
antenna" is not recommended.
