4-Hole Antenna Mast Clamp for Ø 38–42 mm Tubes
This 4-hole mast clamp provides a robust mounting solution for antenna masts and tubes with an outside diameter of 38 to 42 mm.
It is particularly suitable for satellite and antenna installations where a mast needs to be secured to a suitable load-bearing timber structure such as a roof rafter, wooden beam or similar construction.
The clamp is manufactured from 3 mm quality steel sheet and features a galvanised surface. Two 8 × 50 mm wood screws are included.
This makes the mast clamp suitable for new installations as well as repair, replacement and retrofit applications.
Suitable for Ø 38–42 mm mast tubes
The clamp is designed for round mast tubes with an outside diameter between 38 and 42 mm.
Typical applications include:
satellite antenna masts
DVB-T/T2 antenna installations
terrestrial antennas
directional antennas
suitable radio antenna systems
other compatible mast constructions
The actual mast diameter should always be checked before installation.
Robust 3 mm steel construction
The mast clamp is manufactured from 3 mm thick quality steel sheet.
Its robust construction provides a stable mechanical base for fastening a suitable mast tube.
This is particularly important in outdoor antenna installations, where wind loads acting on the antenna are transferred through the mast to the supporting structure.
Four-hole mounting design
The clamp features a 4-hole mounting configuration for attachment to a suitable supporting structure.
The strength of the completed installation depends not only on the clamp itself but also on the mast, antenna, fasteners and mounting substrate.
Important factors include:
mast diameter
unsupported mast length
antenna size
antenna weight
wind surface area
timber quality
screw embedment
edge distances
installation location
Galvanised surface
The steel clamp features a galvanised surface.
According to the available product data, the coating thickness is approximately 0.24 µm.
The coating provides basic corrosion protection for typical antenna and roof installation conditions.
Two 8 × 50 mm wood screws included
Two 8 × 50 mm wood screws are supplied with the mast clamp.
They can be used for suitable timber substrates such as:
roof rafters
wooden beams
timber supports
other appropriate load-bearing wooden structures
The supporting structure must always be suitable for the expected mechanical load.
Suitable for satellite and antenna installations
Typical applications include:
securing a satellite antenna mast
mounting an antenna tube to a roof rafter
DVB-T/T2 installations
directional antenna installations
replacing an existing mast clamp
repairing or upgrading an existing antenna system
A rigid mast connection is particularly important for satellite dishes, as movement of the mast can affect dish alignment and reception quality.
Suitable for new installations and repairs
The clamp can be used for:
new antenna installations
replacement of an existing mast bracket
repair of damaged mounting hardware
retrofit work
relocation of an existing mast
upgrading an existing installation
