Main Product Introduction
This 10-port multiband antenna is a cornerstone for modern macro-cell infrastructure, allowing carriers to support multiple frequency bands (700/800/900/1800/2100/2600MHz) within a single antenna footprint. The antenna is divided into distinct frequency clusters: two low-band arrays (R1/R2) and three high-band arrays (Y1/Y2/Y3), each supporting ±45° polarization for optimal diversity and MIMO performance. A standout feature is the integrated, field-replaceable Remote Electrical Tilt (RET) system. This allows network engineers to adjust the electrical downtilt (2° to 12°) remotely via the AISG 2.0 protocol, significantly reducing the need for tower climbs and optimizing network coverage in real-time. The use of 4.3-10 connectors provides a 40% reduction in connector space and substantial weight savings while maintaining the highest levels of PIM stability. Built to withstand extreme conditions, the antenna is rated for wind velocities up to 216 km/h and features a rugged, UV-resistant fiberglass radome, ensuring a long service life in the most demanding outdoor environments.
Application Scenarios
- 4G/5G Macro Cell Sites: Consolidating multiple frequency bands to reduce tower loading and lease costs.
- Urban Capacity Densification: High-gain 65° sector coverage for high-traffic metropolitan areas.
- Co-location Sites: Ideal for sites shared by multiple operators requiring independent tilt control via AISG.
- Rural Coverage Extension: Leveraging high-gain low-band arrays to extend the reach of LTE and 5G NR services.
- Urban Capacity Densification: High-gain 65° sector coverage for high-traffic metropolitan areas.
Product Q&A
- Q: What is the benefit of the 4.3-10 connector over the traditional 7/16 DIN?
- A: The 4.3-10 connector offers superior PIM performance and is significantly more compact and lightweight. It also separates the electrical contact from the mechanical coupling, ensuring more stable RF performance even when torque varies.
- Q: Can the RET (Remote Electrical Tilt) unit be replaced in the field?
- A: Yes. The RCU (Remote Control Unit) is designed to be field-replaceable. This means if a tilt motor fails, it can be swapped without needing to replace the entire antenna, greatly reducing maintenance costs.
- Q: What does “AISG 2.0/3GPP Protocol” mean for compatibility?
- A: This ensures that the antenna’s electrical tilt can be controlled by any standard Base Station (BTS) or specialized controller that follows these industry-wide protocols, regardless of the manufacturer.
- Q: How does the antenna handle extreme weather?
- A: The antenna is built with a UV-resistant fiberglass radome and is rated to operate in temperatures as low as -50°C. It also features DC grounding for lightning protection and is tested for high wind loads (up to 924N at 150km/h).
