The company is fully committed to reducing the physical size of antennas without compromising performance. As early as 2013, the group had launched a generation (1710 to 2170 MHz) of compact 4G base station antennas, featuring the same-level performance as existing counterparts yet smaller in footprint and more lightweight. Deployments by wireless carriers and industry peers worldwide have led to over 550,000 units being shipped to date. The newly launched next generation of ultra-wideband (1710 to 2690 MHz) compact 4G antennas is the result of the company’s continuous innovations in terms of combining a reduced footprint and wideband technologies.

The antennas are 50 per cent smaller and 40 per cent lighter than conventional antennas. For example, the 1710 to 2690 MHz, dual-port, variable electrical tilt antenna measures 120- x 60-mm and weighs 7.0 kg. The 1710 to 2690 MHz, quad-port, variable electrical tilt antenna has dimensions of 249- x 60-mm and weighs 10.5 kg, while the 1710 to 2690 MHz, hexa-port, variable electrical tilt antenna measures 380- x 65-mm and weighs 15.0 kg.

Other key features include a flat, highly integrated, multi-port, screw-free phase shifter and best-in-class radiation characteristics. The antenna is highly stable and reliable for long-term use, as all core components are produced using automation and raw materials that are supplied by world-renowned brands.

Mr. Zhang Yuejun, Vice Chairman and President of Comba Telecom said, “Compact, multi-band, active mode and intelligent solutions are the development trend of next-generation mobile communication networks and antenna technologies, with the small form factor being the foundation. Based on the results of Comba Telecom’s research into miniaturization technology, our compact antenna technology provides solutions to network construction issues such as difficulties encountered in site selection and base station construction, helping to increase efficiency and reduce costs associated with the build out of base stations.”

“Our R&D team has been at the forefront of technology. In addition to developing compact antenna technologies, we have also upgraded the low gain, ultra-wideband and compact antennas in a concealed design by adopting a new antenna shape and installation method so that the antennas can be installed on traffic light poles, traffic control structures and directional signs on roadways and thoroughfares, without taking up undue space on roofs, poles and towers, and can be naturally integrated with the surrounding environment. The product has been deployed and is now in use in several cities across China due to the unit’s small size and flexible installation.”
