Rooftop lattice steel telecom towers are critical infrastructure for expanding 4G/5G network coverage in urban environments. These structures overcome space constraints by leveraging existing buildings, providing robust support for antennas while minimizing ground footprint. Below is a technical analysis of their design, materials, and deployment.

Applications & Deployment
Urban Sites:
High-Rise Buildings: Extend coverage above obstacles; integrate lightning rods for building protection.
Historic Districts: Lattice aesthetics blend better than monopoles in sensitive zones.
Challenging Terrain:
Mountainous/hilly regions: Towers on elevated buildings bypass line-of-sight barriers.
Coastal zones: HDG resists salt spray corrosion.
Multi-Operator Use:
Platforms accommodate 3+ carriers, each mounting 6–12 antennas per sector for 4G/5G bands.
