Dual-polarized LTE wideband antenna for 4G base station

　　Dual-Polarized LTE Broadband Antenna: A High-Capacity Solution for 4G Base Stations

　　Our dual-polarized LTE broadband antenna addresses the pain points of 4G base stations—from limited user capacity to uneven signal coverage. Designed specifically for global telecom operators, base station infrastructure builders, and network integrators, this antenna utilizes ±45° dual polarization technology to boost 4G network capacity, extend coverage, and ensure stable data transmission in high-traffic scenarios (such as city centers, transportation hubs, and suburban communities).

　　Key Benefits of 4G Base Station Deployment

　　1. ±45° Dual Polarization: Maximizing 4G Network Capacity

　　This antenna utilizes a ±45° dual linear polarization design and supports MIMO (Multiple Input, Multiple Output) technology, allowing data to be transmitted and received via two independent signal paths. This doubles 4G network capacity compared to single-polarization antennas. It supports customizable 2×2/4×4 MIMO configurations, enabling the base station to handle up to 50% more concurrent users (for example, over 300 simultaneous connections in densely populated urban areas) without latency. Dual-polarization technology also reduces signal fading caused by multipath interference (e.g., from buildings and high-rise structures), keeping call drop rates below 0.5% and data throughput consistently above 150Mbps (downlink).

　　2. Ultra-Wide Bandwidth: Global 4G Band Compatibility

　　This module covers all major 4G LTE bands (700MHz–2700MHz), including Bands 1/2/3/4/5/7/8/12/13/17/20/28, seamlessly adapting to global 4G standards (e.g., FDD-LTE and TDD-LTE) used by operators such as Verizon (US), Vodafone (Europe), and China Mobile (Asia). This eliminates the need for multiple single-band antennas per base station, reducing hardware costs by 30% and simplifying tower-top equipment layout. It also supports a smooth migration to advanced 4G networks (such as LTE-A), protecting operators' long-term investments.

　　3. Base-Station Durability: Withstands Harsh Outdoor Environments

　　Designed to stringent 4G base station environmental standards, this device operates stably in temperatures ranging from -40°C to +85°C, enduring both the harsh winters of high latitudes and the scorching summers of tropical regions. Its IP68 waterproof and dustproof rating withstands heavy rain, snowstorms, and sandstorms, making it ideal for base stations in deserts or coastal areas. Its housing, constructed of reinforced fiberglass and corrosion-resistant aluminum alloy, resists rust caused by salt spray or industrial pollutants. It also passes IEC 61000-6-4 interference immunity testing, ensuring it is immune to signal interference from nearby power lines or other base station equipment. 4. Precise Coverage Control: Reduces Inter-Cell Interference

　　The antenna features adjustable beamwidth (horizontal: 30°/65°/90°, vertical: 8°/12° - customizable), allowing operators to tailor coverage to specific 4G base station scenarios: a narrow beamwidth (30°) is suitable for long-range coverage (up to 10 km) in suburban/rural areas, while a wide beamwidth (90°) is suitable for dense urban micro-cell deployments. Low sidelobe levels (<-30dB) minimize signal leakage to adjacent cells, reducing inter-cell interference by 40% and improving 4G signal quality for end users (SINR >20dB).

　　5. Easy Deployment: Compatible with 4G Base Station Infrastructure

　　Designed for seamless integration with 4G base station towers/masts, the antenna supports standard pole/pole mounting (50mm to 114mm diameter) and comes pre-installed with a grounding kit (compliant with IEC 62305 lightning protection standards). Weighing ≤12kg (18dBi gain model), the compact rectangular design (typical dimensions: 600mm × 300mm × 120mm) reduces tower load and simplifies hoisting during installation. Pre-calibrated, plug-and-play operation reduces on-site installation time by 40%, crucial for rapid 4G network deployment.

　　Key Technical Specifications

　　This dual-polarized LTE antenna operates from 700MHz to 2700MHz, covering all global 4G LTE bands and adapting to operator network configurations. The antenna offers adjustable gain (12dBi–21dBi): 12–15dBi for micro base stations (for urban blind spots) and 18–21dBi for macro base stations (for long-range coverage). It supports 2×2/4×4 MIMO configurations, features ±45° dual linear polarization, and a standing wave ratio (VSWR) of ≤1.5, minimizing signal attenuation. This antenna has a maximum input power of 60W (per port) and features a waterproof, sealed 2/4" N-type female connector for secure connection to 4G base transceiver stations. It withstands wind loads up to 280 km/h (compliant with IEC 60728-8), meets IP68 protection standards, and is compliant with CE, FCC, RoHS, and 3GPP (TS 36.104) certifications, ensuring compatibility with global 4G networks.
