Mombasa’s coastal environment presents a tough mix of high winds, salt-laden corrosion risk, and tight installation windows for telecom infrastructure. SOLAR TODO delivered a 33-unit deployment of 30m steel monopole Telecom Towers designed for multi-antenna radio access and microwave backhaul—built for durability, rapid logistics, and compliance with recognized structural standards.
Answer Capsule: SOLAR TODO installed 33×30m steel monopole Telecom Towers in Mombasa using hot-dip galvanized Q345 steel, pile foundations, and CKD logistics—supporting 6 panel antennas and 2 microwave dishes per tower.
Project Overview: Telecom Capacity Expansion for Coastal Operations
This project in Mombasa, Kenya (latitude -4.04, longitude 39.67) focused on expanding telecom coverage and improving backhaul reliability for locations where conventional tower upgrades were constrained by access, staging, and scheduling. The SOLAR TODO solution centered on a steel monopole tower (NOT lattice, NOT FRP) engineered to carry multi-sector antenna tiers and microwave dishes while maintaining structural integrity under coastal wind loading.
Each tower was configured to support: 6× panel antenna + 2× microwave dish (with 2 antenna platforms and 2–3 antenna tiers as required by the layout), plus essential safety and grounding hardware. To match the realities of coastal logistics, towers were shipped in CKD (knock-down) form, achieving 60–70% volume reduction to reduce transport constraints and enable faster site assembly.
Why the Steel Monopole Tower Design Mattered in Mombasa
Mombasa’s coastal conditions increase both mechanical demand and long-term exposure. Wind events require robust design margins, while the salt environment accelerates corrosion if materials and protective systems are not specified correctly. SOLAR TODO’s tower design addressed these challenges through:
- Hot-dip galvanization on Q345 steel to improve corrosion resistance in a low corrosion zone context.
- Tapered round or octagonal steel tube geometry (steel monopole, NOT lattice) to reduce wind-induced vibration drivers compared with more open structures.
- Wind class compliance aligned to TIA-222-H with a 40 m/s design basis and factor 1.
- Flanged bolt-on sectional design to support field assembly and predictable alignment during commissioning.
From a deployment standpoint, the CKD shipping approach (60–70% volume reduction) was critical. It allowed the project team to stage more components per shipment, reduce oversize transport friction, and shorten the time between delivery and installation.

Tower Configuration Delivered: Multi-Tier RF Support and Backhaul
Each 30m Telecom Tower was delivered as a flanged, bolt-on sectional structure. The design supported 2–3 antenna tiers depending on site-specific RF planning, with the final installed configuration providing 6× panel antenna for sector coverage and 2× microwave dish for backhaul.
To make the installation maintainable and serviceable for ongoing network operations, SOLAR TODO included:
- Two antenna platforms sized and positioned to support safe technician access and routine inspection.
- Climbing ladder integrated for vertical access from base to working levels.
- Cable tray routing to keep RF and auxiliary cabling organized and protected along the mast.
- Safety cage to reduce fall risk during maintenance activities.
- Grounding system and lightning rod to support lightning protection and electrical safety.
- Aircraft warning light to meet aviation obstruction marking requirements (aligned with common FAA/ICAO-style practices used in telecom tower deployments).
Foundation and Site Integration: Pile_foundation for Coastal Stability
For this Mombasa deployment, SOLAR TODO used pile_foundation to address ground conditions typical of coastal development zones—where soil variability and water table effects can complicate shallow pad-only solutions. The pile foundation approach provided a stable load path for the tower’s ~15t structural mass and wind overturning forces.
Installation sequencing was planned to reduce downtime and keep work areas clear for surrounding site activity. With the CKD approach, the erection team could stage sections efficiently, then assemble the tower using the flanged bolt-on design to ensure consistent section alignment.
Logistics and Manufacturing: CKD to Reduce Transport Constraints
Transporting full-height towers to multiple Mombasa sites can be challenging due to route constraints, staging limitations, and coordination with local authorities and site owners. SOLAR TODO mitigated these constraints with CKD shipping:
- 60–70% volume reduction per shipment
- 30–45 days production cycle per batch
- 60–70% reduced shipping volume improved the practicality of delivering to distributed sites without oversized logistics bottlenecks.
This also helped the installation team maintain a predictable workflow: arrive with staged sections, assemble, integrate grounding and lightning components, mount antennas and microwave dishes, then complete commissioning checks.
