Radar Towers
& Monopoles
FLI designs, manufactures and installs radar towers and radar monopoles for military and civil aviation applications worldwide. Our structures are engineered for tight deflection limits, high wind loadings and demanding environmental conditions, providing reliable long-term support for radar systems in airports, coastal locations and remote global sites.
Radomes
Radomes are used to protect antenna surfaces from the weather and to screen equipment from view. They add a significant wind loading to the structure and come with their own requirements for installation and maintenance.
FLI have experience in both defence and civil markets, supplying and installing towers carrying radomes into some of the worlds most remote sites that experience sustained extreme weather loadings.
Terma Radar
FLI supplies towers to support Terma Surface Movement Radar Systems used at major airports, as well as Terma Mitigation Radar, which counters interference to traffic-control radar caused by nearby wind farms.
Slim radar towers with a ladder and fall-arrest system are commonly supplied, although larger lattice towers with staircases are also available. Various foundation systems can be used, including concrete, screw piles or micropiles for challenging ground conditions.
Congested Sites
FLI’s engineering, manufacturing and installation teams operate under one roof, enabling efficient development of high-quality, practical solutions for radar tower installations in constrained or complex environments.
Tacan Radar
The FLI SLP4 tower is a slim parallel tower with a ladder and Latchway fall arrest. This example was used for a TACAN antenna, with a platform for safer access for maintenance and future upgrades.
Radar Monopoles
A monopole solution was introduced for supporting Surface Movement Radar at airports and wind farm mitigation systems. Monopoles are sometimes preferred by the airports as they are less visually intrusive and require a smaller demise within busy airport sites. Monopoles can be supplied galvanised or painted ICAO colours.
Hybrid Lattice Towers
FLI are leaders in the design, supply and installation of Hybrid Towers throughout the UK. Hybrid Towers are steel lattice from ground level, interfacing with a timber lattice upper section. Typically between 15m and 50m in height, Hybrid Towers are used for mounting “ground to air” communications antenna for both military and civilian markets. FLI design these structures in-house to BS8100/Eurocode and for site specific loadings and our clients requirements.
Installation Teams
FLI Structures has complete in-house capabilities to install any steel structure, from rooftop mounted radar to 300 metre masts. FLI towers and masts have been installed by FLI crews around the world from the Falklands to Norway. The cost and risk benefits to customers from FLI offering a full turnkey solution are significant.
