3 m Ballasted Terrace and Flat-Surface Stand – Ø 60 × 2 mm Sectional Mast for Satellite, Radio and Suitable Small Wind Generators
The AS21020 is a heavy-duty ballasted mast stand designed for suitable terraces, flat roofs and other level installation surfaces.
According to the available product data, the structure is manufactured from hot-dip galvanised steel and uses a 3 m sectional mast with an outside diameter of Ø 60 mm and a wall thickness of 2 mm.
The mast can be tilted by up to approximately 2° for minor alignment.
The base is designed to accept 50 × 50 cm concrete slabs, which are not included.
According to the basic product data, the frame is intended for four slabs. Additional product information states a minimum of four slabs and currently recommends 16 slabs. The actual ballast required must, however, be determined from the complete installation and local wind conditions.
3 m sectional mast
Mast specifications:
Height: 3000 mm
Diameter: Ø 60 mm
Wall thickness: 2 mm
Design: sectional / plug-together mast system
The sectional design makes transport and handling easier than with a single 3 m tube.
Hot-dip galvanised steel
The structure is manufactured from hot-dip galvanised steel according to the product data.
This supports corrosion protection for permanent outdoor installation.
Additional bracing
According to the additional product information, the mast structure uses four additional support braces.
These help stiffen the connection between the mast and base frame.
Ballasting with 50 × 50 cm concrete slabs
The base accepts concrete slabs measuring:
50 × 50 cm
The slabs are not included.
The number of slabs alone does not define the stability of the system. Slab thickness and actual total ballast mass are also important.
Ballast depends on the complete installation
Required ballast depends on factors such as:
mast height
attached equipment
wind area
installation height
building height
local wind conditions
position on a roof or terrace
dynamic loads
Mast adjustment up to approximately 2°
The mast can be tilted by up to approximately 2°.
This can assist with minor alignment and compensation for small deviations in the installation surface.
Anti-slip rubber feet
Anti-slip rubber feet support stable contact with suitable surfaces and reduce direct metal-to-surface contact.
They do not replace adequate ballast.
Satellite applications
The AS21020 can be used as a support for suitable satellite antennas on:
terraces
suitable flat roofs
other suitable level outdoor surfaces
No specific maximum satellite dish diameter is stated in the available data.
Radio and communication applications
Depending on the total mechanical load, the mast can also be used for suitable:
DVB-T/T2 antennas
DAB/DAB+ antennas
FM antennas
WLAN antennas
directional radio antennas
communication equipment
Cameras and measuring equipment
Suitable cameras, sensors, weather instruments and measuring equipment may also be mounted, provided weight and wind area are compatible with the mast system.
Suitable micro and mini wind generators
According to the available product data, the stand is also intended for suitable micro and mini wind generators.
Wind turbine installations create additional dynamic loads including:
rotor forces
vibration
alternating wind loads
torque
cyclic mechanical stress
The turbine must therefore be checked for compatibility with the Ø 60 mm mast and the complete stand.
Flat-roof installations
When installed on a roof, particular attention must be paid to:
permissible roof load
total ballast mass
point loads
roof membrane protection
drainage
wind uplift
roof edge zones
Regular inspection
For permanent outdoor installations, regularly inspect:
mast connections
support braces
ballast
mast alignment
rubber feet
mounted equipment
Wind generator installations should additionally be checked for vibration-related loosening.
