Over the past 30 years, Carl C. A/S has been among the preferred telecommunications suppliers in Europe.

 Telecommunications started with the NMT system in the 1980s with multiple deliveries to TDC NET, the former Statens Teletjeneste. After that, the GSM 900 network was established. Then came GSM 1800, the 3G network, UMTS and the 4G network, LTE.

An increasing demand for mobile telephony and access to high-speed Internet services means that telecom companies have had to increase capacity and coverage by expanding their networks with more masts, etc. The future roll-out of 5G will only increase demand. The height of a mast depends on many factors, but usually masts are between 24 and 48 metres in height.

Carl C. A/S supplies many different types of mast for telecommunications purposes.

As an alternative to the lattice mast, we produce several types of tubular structures in the form of false chimneys, flagpoles etc. whose purpose is to conceal the masts. This provides more options for placing telecom masts in areas where aesthetics are given high priority, e.g. to meet requirements made by landscape architects.

Our long association with Danish telecoms companies means that all types have been tested over several years.  

Lattice masts

The Series 16 mast is square, specially developed for the telecoms industry around 1990. It was the most-used lattice mast in Denmark until the launch of the TEL range in 2008. The mast is suitable as a multi-user site where the load is large, and deflection needs to be small. This range of masts is mainly made of solid rod iron which results in a transparent design.

The TEL mast is a slim, three-legged mast measuring 24–28 metres in height. This mast was especially developed for the telecom industry. It is the next generation of the highly popular Series 16. 
Telecom companies in Denmark have preferred this mast and use it as their standard mast throughout Denmark. A very large number have been sold since 2008.
The advantages of the TEL mast lie in its slim, triangular design which is always fully optimised to meet the application concerned. At the same time, most of the mast consists of solid round-steel bars which, in combination with the slim design, make the mast appear almost invisible in the landscape.
As pipes are only used very sparingly, wind noise from open profiles is not a problem.

We offer the mast in a reinforced version for installation in coastal areas.

 TEL gittermast


The CHS mast is the latest model within lattice masts. Specially designed for ease of transportation. Compared to the Series 16 and TEL masts, which are fully-welded, the CHS mast is bolted together. This makes it possible to assemble it on-site if necessary. Hollow tubing is also used, to make it light and easy to transport. Perfect for areas where access can be difficult.

As an alternative to our lattice masts, we provide pipe masts in standard heights from 21 to 42 metres. These can be used by one or more operators.

Tubular masts

Telecom companies in Denmark have used our tubular masts at many sites all over Denmark, which means that the product has been tried and tested over several years.

The advantages of the tubular mast are its slim, rounded design that makes the mast appear light and elegant and conceals cabling completely. Therefore, the appearance of the tubular mast differs from a lattice mast and may be used in situations where lattice masts are not wanted.

The tubular mast comes with a hot-dip galvanised finish, but can also be painted to achieve a completely uniform exterior. Access ladders can also be installed for easy access to the aerials. 



Telescopic masts

Our telescopic Turbo mast is a top-quality product designed for professional use in locations where function, quality and service life are a priority. Our telescopic Turbo mast comes with a maximum height of 21 metres and consists of three sections as well as a tilt section.

The tilt section is used to raise the mast from its horizontal starting point to its vertical position after which it is ready to be extended to its full height. All functions are carried out using electric winches.

All sections of the mast are equipped with corrosion-resistant guide rollers to ensure very precise movement. When the sections hit their top position, they are locked into place to prevent play.

Our telescopic Turbo mast can be used as a stationary mast where easy access is required to adjust or replace equipment at the top of the mast. The mast can also be used for mobile-network purposes in telecommunications, monitoring etc.


False chimneys    

False chimneys are used where a concealed solution for up to four operators is required. This is a new and innovative product that has been used by the telecommunications industry since 2010.

The advantages of the Chimney mast lies in its slim and rounded design that allows concealed aerials and cabling. Our chimney masts are made of tubular steel which, with their light grey painted surface, make the chimney blend in seamlessly with the surrounding landscape.

Chimney masts are available in heights of up to 42 metres and have the same diameter from base to top of Ø813 mm. The top 12 metres are divided into four sections of three metres each. This allows each operator space for panel aerials and mini-links. The aerials are concealed by coloured styrene panels which do not impair aerial performance.
