3.3 Installation precautions
3.3.1 Radiation hazard
The SAILOR FleetBroadband antennas is radiating RF energy
harmful to the human body. Therefore whenever the system is
powered, make sure that personnel is not near the antenna.
Though it is only when the SAILOR FleetBroadband antenna is
transmitting, and then only in front of the antenna. But as the is not
visible by the antenna to see when it is transmitting and in which
direction a whole circle around the antenna should be considered
as a hazard zone.
Bare in mind that the antenna panel can be elevated to below
horizontal as follows:
• SAILOR 500 FleetBroadband = -25º
• SAILOR 250 FleetBroadband = -60º
• SAILOR 150 FleetBroadband = -60º
SAILOR 500 FleetBroadband antennaa are radiating up to
22 dBW EIRP (158.5 W). This translates to a minimum safety
distance of 1.3 m from the antenna based on a radiation level of
10 mW/cm
2
.
SAILOR 250 FleetBroadband antenna is radiating up to 16.1
dBW EIRP (41 W). This translates to a minimum safety distance of
0.6 m from the antenna based on a radiation level of 10 mW/cm
2
.
SAILOR 150 FleetBroadband antenna is radiating up to 16.1
dBW EIRP (41 W). This translates to a minimum safety distance of
0.6 m from the antenna based on a radiation level of 10 mW/cm
