Frangible Lattice Mast DKE200
Features
• Meets ICAO and FAA standards
• Built in frangibility
• Fully impact tested
• Transparent to electromagnetic radiation – no interference with airport communication equipment
• Optional passive air terminal protects sensors and other equipment
• Composite structure provides superior air terminal insulation
Vaisala Frangible Lattice Mast DKE200 is a lightweight and rigid mast especially suited for aviation use. The mast complies with ICAO and FAA standards and is compatible with all Vaisala weather stations.
Fully compliant with safety specifications
The DKE200 mast materials comply with aviation safety specifications and the mast is impact tested according to the ICAO Aerodrome Design Manual Part 6, chapter 5 and FAA AC 150/5345 45C, section 4.
The DKE200 mast is rigid and strong but lightweight, and its composite structure makes it brittle in case of sudden impact. In collision, the mast breaks at the point of impact without causing hazard to the aircraft.
Robust and corrosion-resistant build
The DKE200 mast withstands wind speeds of up to 60 m/s (134 mph). The composite materials resist fatigue, corrosion, and other effects of weather and temperature, making the masts also suitable for marine and other corroding environments.
As composite materials do not distort electromagnetic signals of the airport communications equipment, the need to calibrate instrument landing system (ILS) antennas is reduced.
The DKE200 mast is maintenance free.
Custom options for all kinds of airports
The mast is supplied with a bottom hinge, allowing maintenance from a crane truck without lowering the mast. A center-hinged version is also available, allowing the mast to be lowered by a single maintenance worker for easy maintenance of the sensors and other equipment. Note that the number of persons needed depends on local safety regulations.
An optional passive air terminal is available for protecting sensors and other equipment. The composite materials of the mast provide superior air terminal insulation.
