HONG KONG SAR – Media OutReach – 15 February 2023 – Comba Telecom Systems Holdings Limited (“Comba Telecom” or “the Group”, SEHK stock code: 2342 and SGX stock code: STC), a global leading wireless solutions provider, today unveiled its Green Base Station Antenna product series powered by the new and innovative Helifeed� Platform, achieving leap-forward antenna energy efficiency, and optimizing antenna energy consumption. With green and low-carbon design concepts incorporated throughout the entire product life cycle, Comba Telecom offers forward-thinking Helifeed™ Green Antennas to support operators in achieving carbon neutrality targets worldwide.

The new Helifeed™ Platform laid a solid foundation by adopting multiple innovative technologies related to phase shifters and feeding network to create a path to a carbon-neutral radio network.

Featuring the industry-leading low-loss, high-efficiency, and low-carbon Green Antenna, the Helifeed™ Green Antenna product series can extend the mobile coverage or as a one-to-one replacement with the same mobile site coverage, to reduce the energy consumption and carbon footprint of the networks. By the end of 2022, over 50,000 pieces of the Heilifeed™ Green Antennas have been deployed by major APAC operators, and the new innovative technology platform has been verified in multiple tier-1 operators’ trial networks. The results are convincing in terms of creating additional antenna gains over traditional antennas to cut the site energy consumption effectively.
