Drone Detection and Communications Towers
FLI lattice towers provide elevated structural support for drone detection, counter-UAS, communications and surveillance equipment across defence installations, critical infrastructure and security-sensitive sites.
Working with system integrators and equipment suppliers, FLI develops tower configurations to meet coverage requirements, equipment loads, mounting heights, site constraints and environmental conditions.
Structures can accommodate multiple antennas, RF equipment, sensor arrays and detection systems, with headframes, antenna poles, platforms, cable management and access systems tailored to equipment layouts.
Using existing lattice tower designs or project-specific engineering, FLI can also provide flexibility for future equipment upgrades.
Radar Towers
FLI designs, manufactures and installs towers and monopoles for radar applications in the UK and overseas, including defence and surveillance installations in remote and exposed locations.
Structures can be engineered around radar equipment loads, mounting interfaces, access requirements and site-specific environmental conditions.
Temporary and Rapid Deployment Towers
FLI modular temporary towers, available up to 30m in height, can support temporary communications, surveillance and detection equipment where permanent structures are unsuitable.
With steel kentledge foundations removing the requirement for piling or concrete, systems can accommodate associated equipment cabinets and generators, and be dismantled and redeployed between sites.
Foundations
FLI designs and manufactures foundation systems for towers, monopoles and equipment support structures across permanent and temporary installations.
Options include screw pile foundations, driven piles, steel grillages and kentledge systems, with foundation design considering structural loading, ground conditions, access and installation constraints.
Alternative foundation systems can reduce excavation, concrete, heavy plant requirements and ground disturbance at remote, restricted-access and sensitive sites.
Design, Manufacture and Installation
FLI provides structural design, manufacture, foundations and installation for defence, radar, surveillance and drone detection infrastructure.
Our engineers can work with system integrators, equipment suppliers and project teams using equipment loads, mounting interfaces and site data to select an existing FLI structure or develop a project-specific solution.
Applications include:
-
Counter-UAS and drone detection
-
Radar and sensor systems
-
Air and maritime surveillance
-
Perimeter and site security
-
Communications and antenna systems
-
Critical infrastructure monitoring
-
Temporary and rapidly deployed systems
