Adjustable Sliding Mast Bracket for Tubes up to Ø 60 mm – Offset up to 250 mm
The AS46105 is an adjustable mast mounting bracket designed for satellite and antenna mast tubes up to Ø 60 mm.
It is particularly useful for under-roof installations where the desired mast penetration through the roof is not positioned directly in front of the roof rafter.
According to the available product data, the mast position can be adjusted up to approximately 250 mm from the rafter or mounting surface.
The mounting plate measures approximately 70 × 120 mm, and the steel construction is galvanically zinc plated.
For mast tubes up to Ø 60 mm
The mast holder is suitable for tubes with an outside diameter of:
up to Ø 60 mm
The actual mast diameter and wall thickness should be checked before installation.
Adjustable up to 250 mm
The mast position can be adjusted up to:
approx. 250 mm
approx. 25 cm
from the mounting surface.
This allows the mast axis to be aligned with a suitable roof penetration even when the rafter is positioned to one side.
Useful for roof penetrations
The sliding design can make it easier to align the mast with a suitable:
antenna roof tile
roof flashing
mast penetration point
without forcing the mast to follow the exact position of the rafter.
Roof tile removal depends on the roof design
Legacy product information suggests that only one roof tile may need to be removed.
This may be possible in suitable installations, but it depends on:
roof tile geometry
rafter location
mast diameter
type of roof flashing
roof pitch
It should not be treated as a universal installation guarantee.
Mounting plate approx. 70 × 120 mm
The mounting plate measures approximately:
70 × 120 mm
according to the available product data.
Galvanically zinc-plated steel
The mounting bracket is manufactured from galvanically zinc-plated steel.
Roof rafter mounting
A typical application is attachment to a structurally suitable roof rafter.
The timber must be capable of carrying the loads created by:
mast weight
antenna weight
wind forces
mounting offset
Offset creates leverage
The adjustable range of up to 250 mm provides useful installation freedom but also increases leverage.
The mast should therefore be positioned only as far from the support as required by the installation.
Wall mounting
According to the available product information, wall mounting is also possible in suitable configurations.
Depending on mast length and loading, more than one mounting point may be required.
Separate roof sealing required
The AS46105 is a structural mast mounting component.
It does not itself provide the complete weather seal where the mast passes through the roof.
A suitable:
roof tile
roof flashing
mast collar
sealing sleeve
must be selected separately.
Satellite and terrestrial antenna applications
Depending on the complete mechanical design, the bracket may be used for suitable:
satellite antennas
DVB-T/T2 antennas
DAB/DAB+ antennas
FM antennas
radio antennas
No maximum antenna size specified
No confirmed maximum satellite dish or antenna size is available.
Suitability depends on the complete structure, particularly mast length, antenna wind area, support condition and selected offset.
