Complete Roof Mast Installation Set for Ø 50 mm Antenna Masts – Brick Red
The AS44550 is a complete installation set designed for mounting and routing a Ø 50 mm antenna mast through a pitched tiled roof.
The set combines mechanical mast support components with a brick-red aluminium roof flashing, sealing collar and mast cap.
According to the available product data, the set is specifically intended for antenna masts with an outside diameter of 50 mm.
Complete installation set
The package includes:
1 × brick-red aluminium roof flashing tile, 450 × 500 mm
1 × mast clamp for Ø 50 mm
1 × galvanised mast base
galvanised steel fixing hardware
1 × brick-red UV-resistant sealing collar
1 × UV-resistant plastic mast cap
Specifically designed for Ø 50 mm masts
Unlike universal clamps covering a broad diameter range, the AS44550 is intended for Ø 50 mm antenna tubes.
The actual mast diameter should therefore be checked before installation.
Mast base and additional clamp
The mast can be supported at two points using the mast base and the Ø 50 mm clamp.
This supports stable mast guidance and helps reduce unwanted movement.
The final structural performance still depends on mast dimensions, support spacing, antenna size and wind load.
Aluminium roof flashing 450 × 500 mm
The supplied roof flashing measures:
Length: 450 mm
Width: 500 mm
According to the available product data, it combines aluminium with UV-resistant plastic components.
The brick-red finish is particularly suitable for red and terracotta-coloured roof coverings.
Adaptable to many roof tile profiles
The formable aluminium section can be adjusted to many common roof tile contours.
Compatibility should nevertheless be checked against the actual roof profile before installation.
UV-resistant sealing collar
The supplied brick-red sealing collar supports the weather-protected connection between the Ø 50 mm mast and the roof flashing.
Correct seating and proper integration into the roof covering are essential.
UV-resistant mast cap
The mast cap provides a weather-protected upper closure for an open antenna mast and reduces direct ingress of rain, dirt and foreign objects.
Suitable for different antenna systems
Typical applications include:
satellite antennas
DVB-T/T2 antennas
DAB/DAB+ antennas
FM antennas
combined antenna systems
Structural considerations
The final mechanical stability depends on:
mast wall thickness
mast length
spacing between support points
free mast projection
antenna weight
antenna wind area
roof structure
fixing hardware
Correct roof integration required
The set supports a weather-protected roof penetration, but proper installation must also include:
correct overlap
controlled rainwater drainage
correct seating of the sealing collar
integration with surrounding roof tiles
consideration of the roofing underlay
