Heavy-Duty Roof Rafter Mast Mount with Ø 60 mm Mast – for Rafter Spacing up to 1100 mm
The AS51521 is a heavy-duty roof rafter mounting system designed for larger and mechanically demanding satellite and antenna installations.
The integrated mast measures 60 mm in outside diameter, 3 mm in wall thickness and 1150 mm in length.
The mounting structure is suitable for rafter spacing up to 1100 mm and roof pitches from 25 to 56°.
According to the available product data, a bending moment of 1100 Nm is specified.
Heavy-duty Ø 60 × 3 mm mast
The mast dimensions are:
Outside diameter: 60 mm
Wall thickness: 3 mm
Length: 1150 mm
The substantial tube dimensions make the system suitable for larger and heavier antenna installations.
Suitable for larger satellite systems
Typical applications include:
larger satellite dishes
heavier parabolic antennas
multi-satellite systems
professional reception systems
bidirectional satellite communication equipment
satellite internet installations
Up to 1100 mm rafter spacing
The bracket is designed for roof structures with rafter spacing up to 110 cm.
Roof pitch from 25 to 56°
The mounting system is suitable for pitched roofs between 25 and 56°.
Bending moment 1100 Nm
According to the available product data, the bracket is designed for a bending moment of 1100 Nm.
The actual suitability of the complete installation also depends on:
antenna size
antenna weight
wind surface area
free mast length
rafter dimensions
roof structure
installation height
local wind conditions
Galvanised steel construction
The bracket is manufactured from galvanised steel and is suitable for typical permanent outdoor roof installations.
Eight 8 × 120 mm fixing screws included
Eight plate-head fixing screws measuring 8 × 120 mm are included.
The suitability of the screws for the actual roof timber construction should be checked before installation.
Suitable for bidirectional satellite systems
The rigid mast design can also be useful for compatible two-way satellite communication systems where stable antenna alignment is particularly important.
Installation on roof structures with counter battens
Where counter battens are present, the bracket must be fixed correctly to the load-bearing rafters.
Any modification to the roof build-up should be carried out without compromising roof sealing or structural integrity.
