Green Antenna Technology: Supporting More Sustainable Mobile Networks
As mobile network operators expand 4G and 5G coverage, improving energy efficiency and reducing carbon emissions have become strategic priorities. Antennas are a critical part of the radio access network (RAN), directly influencing network performance, power consumption, and environmental impact.
Comba’s Green Antenna portfolio is designed to help operators build more sustainable and cost-efficient networks by combining advanced antenna engineering with innovative low-loss feeding technologies.

Helifeed Technology: High-Efficiency Direct Feeding
At the core of Comba’s Green Antenna solution is Helifeed, an innovative direct-feeding architecture that connects the phase shifter and feeding network directly to each dipole.
This design significantly reduces losses found in traditional antenna architectures, where longer cables and more components can degrade efficiency.
Key Benefits of HeliFeed Technology
- Ultra-low insertion loss for improved RF efficiency
- Higher antenna gain and better overall performance
- Reduced CO₂ emissions through lower energy consumption
- Lightweight and compact design
- Fewer components, improving reliability and manufacturability
- Modular architecture for easier integration
- Lower environmental impact through material reduction
Why Low Insertion Loss Matters
In a conventional antenna, RF signals pass through multiple cables and components before reaching the radiating elements, creating losses that require more input power to achieve the desired coverage.
Comba’s HeliFeed technology minimizes these losses by simplifying the signal path. The result is:
- Improved energy efficiency
- Reduced operating expenses (OPEX)
- Lower site power consumption
- Enhanced network sustainability
Environmental and Operational Benefits
Green Antennas contribute to operators’ ESG and net-zero goals by:
- Reducing electricity consumption across the network
- Lowering greenhouse gas emissions
- Decreasing raw material usage
- Simplifying manufacturing processes
- Reducing transportation and installation costs through lighter products
Designed for Modern 4G and 5G Networks
Comba Green Antennas are ideal for mobile operators seeking to:
- Improve base station energy efficiency
- Reduce total cost of ownership (TCO)
- Meet sustainability and ESG objectives
- Enhance network performance without increasing power consumption
