Usually located in remote areas without power grid, met towers needs the use of autonomous beacons powered by solar energy, such as IV-4.1 and IV-4.2. These units meet ICAO requirements for Low Intensity beacons Type A and Type B, respectively.
Their different models can be powered by solar energy, electric power or hybrid power (solar + electric). In this last case they can be used with maximum safety and reliability, both in environments with no access to the network and in places with the risk of electric power cuts.
For towers higher than 45m it will be necessary to install Medium Intensity beacons, such as MIB-1.1 or MIC-1.1, which comply with ICAO / ICAO requirements for Medium Intensity beacons, Type B and Type C respectively.
