Assembly for chemical anchors - description of the technique
Read more: Assembly for chemical anchors - description of the technique.Most of our wall-mounted masts are installed using chemical anchors and threaded rods. This is a very convenient and durable method, though it is sensitive to installation errors. The forces acting on the bolts—especially for taller and more heavily loaded masts—can reach values measured in metric tons, so the quality of the mounting is crucial. General note: if you are not a professional installer…

Reactions to building structure – what should I know?
Read more: Reactions to the building structure – what should I know?Customers often wonder why the mast mount is more expensive than the mast itself. The values of the pulling and driving forces in the roof quoted in the static calculations show how important proper anchoring is, which often requires serious construction works and specialized solutions, individually tailored to each building.

Anti-fall system – what is it and how does it work?
Read more: Anti-fall system – what is it and how does it work?Working on towers and masts can be dangerous. Manufacturers’ recommendations are clear: work at heights should not be performed when wind speeds exceed 5 m/s. Safety harnesses or mountaineering harnesses are helpful in everyday work—they significantly increase safety, albeit at the expense of comfort. Changing position on a mast is particularly cumbersome: every step requires repositioning the lanyard, which in practice leads even experienced…

I'm putting the mast/tower on the ground - how should I foundation it?
Read more: I'm putting a mast/tower on the ground - how should I foundation it?The general rule is that a foundation should not extend below the groundwater level. If the groundwater table is shallow, the most common solution is a foundation slab weighted down with earth fill or shallowly buried precast elements (so-called “mushrooms” from the F series, e.g., those manufactured by Elbud Gdańsk). Cast-in-place slabs are also used in mountainous areas, where just below the ground surface there are…

How to remove lightning from a mast safely? Basic knowledge.
Read more: How to remove lightning from a mast safely? Basic knowledge.When installing lightning protection for telecommunications masts, three main issues must be taken into account. In our opinion, the best and most cost-effective way to dissipate the electrical charge is through the structure of the mast or lattice tower itself. AluPro products are equipped with a special eyelet in the lowest segment, which allows the entire structure to be connected to the building’s lightning protection system. For painted structures, be sure to remove…

Mast and tower service – what should I know?
Read more: Mast and tower service – what should I know?Radio masts and towers require regular inspection and maintenance to prevent breakdowns and life-threatening incidents. Aluminum masts are resistant to corrosion, but susceptible to frost cracking. The condition of guy ropes and rope tension should be checked, and regular anti-corrosion inspections of steel structures are necessary.

Do I have to report radio wave emissions to any department (e.g. environment)?
Read more: Do I have to report radio wave emissions to some department (e.g. environment)?Setting aside the issue of licenses for specific frequency bands, it is worth noting the issue of electromagnetic radiation in the context of its environmental impact. Current regulations allow for power emissions of up to 15 W per antenna without the need to report this to the Department of Environmental Protection—in such cases, the installation is not considered a project with a significant environmental impact.

Do I have to paint my mast with red and white stripes?
Read more: Do I have to paint my mast with red and white stripes?Regardless of the mast’s location (on the ground or on a building), structures under 50 meters in height do not require notification to the competent military aviation oversight authority (for civil aviation, this threshold is 100 meters). The legal basis is the Regulation of the Minister of Infrastructure of June 25, 2003, on the procedure for reporting and marking aviation obstacles (Journal of Laws No. 130, item …

In my area, the County Office expects PnB in relation to the mast on the building - is it right?
Read more: In my area, the County Office expects PnB in relation to the mast on the building - is it right?There is much to suggest that this is not the case. Judgment II SA/Gd 329/14, issued by the Provincial Administrative Court in Gdańsk, is currently in force. In the reasoning for the appellate judgment in this case (i.e., a building permit for a mast on a building), the Court cited Article 29(2)(15) of the Construction Law, as well as Article 30(…

Does a radio mast require a building permit?
Read more: Does a radio mast require a building permit?Masts below 3 meters do not require a permit. Masts over 3 meters on buildings are subject to notification unless local regulations require a building permit.
