VISLINK
Newswift 90-180 Motorised Antenna 4
ADDITIONAL SAFETY INFORMATION
Most of the microwave energy
is contained within this beam
Close Up View
Far View
The European Standard that defines power levels is ETS300327.
The microwave power density limit is 10w/m sq.
For a 125w amplifier and 1.2m antenna, the shaded area represents power levels above the
limit. Outside of this area, the power level is below the limit.
This example shows the beam at 21 deg elevation.
The distance R (m) is approximately
R = antilog (eirp/20 - 1.05) where eirp is dBw.
STOWAGE WARNING
If the Newswift antenna is fitted to a vehicle, ensure that it is stowed when the vehicle is in
motion. The antenna has not been designed to be deployed in this condition and the
resulting forces may exceed the design criteria.
Care should be taken that nothing obstructs the antenna when it is moving as injury or
damage to the antenna or its surroundings may result.
