Ballast masts are structures designed for the installation of antennas, lighting, signalling or other equipment on roofs and other flat surfaces, without interfering with the structure of the ground. Their stability is ensured by appropriately selected ballast (usually concrete weight plates), which prevents the mast from toppling under the influence of wind or vibrations. Ballast masts are widely used in temporary and permanent installations, particularly where permanent anchoring of the mast is not possible or where the integrity of the roofing is required. A variety of mast heights are available as required and the ballast weight is selected to meet the safety requirements of the wind zone. The size of the ballast frames / ballast has been selected so that they can be lifted onto the roof even through a small roof hatch.

DIPOL offers 5 models of ATLAS ballast masts in its shop, designed for various installation applications. Each is characterised by different design features, such as height, load capacity, number of sections or assembly method, allowing the solution to be tailored precisely to the individual user's needs.

ATLAS ballast masts are designed for stable and secure installation of antennas without interference with the roof structure. Thanks to the use of appropriate materials and a well-thought-out design, they ensure high resistance to weather conditions, including strong wind or precipitation. The variety of available models makes the DIPOL offer suitable for both home and professional antenna systems.

The ZB-500/38 RAM2/415×265 E8747 and ZB-500/50 RAM2/400×400 E8749 non-invasive ballast masts are designed for mounting antennas, weather stations and cameras on flat, stable surfaces without interfering with the roof structure. Both models have a mast length of 0.5 m and are equipped with a vertical mast adjustment mechanism from 0 to 5°. However, they differ primarily in their purpose, dimensions and design. The E8747 with a 38 mm diameter mast is more versatile and will be suitable for TV antenna installations, data transmission systems and CCTV monitoring. It has a smaller base measuring 61 × 41.5 cm and uses two concrete blocks measuring 38 × 24 × 12 cm as ballast elements. It is lighter - weighing around 5.9 kg - and less expensive. Its compact design makes it suitable for locations with limited installation space. The manufacturer declares that a mast loaded symmetrically with two concrete blocks of dimensions: 38x24x12 cm (2 x 21 kg) remains stable with a side load of up to 20 kgf applied 5 cm below the top of the mast. The E8749, on the other hand, was designed primarily for antennas dedicated to the STARLINK system, as evidenced by its larger mast diameter of 50 mm. Its base is wider and more massive - measuring 93.5 × 42.5 cm - which allows higher stability of the whole structure. In this case, two larger 40 × 40 cm concrete blocks are used and the weight of the set without blocks is approximately 7.2 kg.

Especially noteworthy is the ATLAS-11 ZB-1100/50 E8748 model designed by DIPOL engineers for mounting satellite dishes. Mounting a satellite dish with a diameter of 120 cm on a ballast mast is performed in situations where there is no possibility of permanent fixing to the building structure, e.g. on flat roofs covered with roofing felt or membrane. The ballast solution allows the antenna to be stably positioned without interfering with the ground, provided that the appropriate safety rules are observed. The ballast base must have sufficiently distributed ballast to ensure wind resistance. In staggered constructions, min. 150 kg and in compact structures approximately 300 kg of ballast for a 120 cm diameter antenna. The mast should be fixed to the base in a rigid manner using high strength bolts. The ballast can be made of concrete blocks or paving slabs, mounted on rubber pads to protect the roofing.
