- Removal & recycling logistics for decommissioning projects
Antenna & Telecommunications Infrastructure
High-performance communications — delivered with precision from the air
For network operators, authorities, and infrastructure providers, we install and maintain telecommunications towers, microwave antennas, and data-transmission systems at exposed sites. Whether mountaintops, rooftops, or forest clearings — helicopters deliver what the network needs.
Services:
- Installation of telecommunications towers
- Delivery of antennas, satellite dishes, and transmission systems
- Component replacement without ground access
- Supply of remote relay stations
Emergency transport & repair missions
When access is compromised — we deliver the solution from the air.
When storms, lightning, or ice damage key infrastructure, rapid response is essential. Heliswiss transports personnel, parts, and equipment directly to critical points. With fast deployment and precise planning, we minimize outage times — safely and efficiently.
- Ad-hoc missions for fault resolution
- Material & tool transport
- Delivery of technical equipment & maintenance teams
- Evacuation or retrieval during extreme weather
Sustainable energy deserves efficient solutions — Heliswiss International AG delivers them from the air.
