This detailed product description introduces a specialized 3.7–4.2 GHz Omnidirectional Outdoor Waterproof Antenna. Operating within the globally critical C-Band spectrum, this antenna is engineered to provide comprehensive, wide-area coverage for high-capacity 5G and Fixed Wireless Access (FWA) networks. Its omnidirectional radiation pattern, combined with rugged, waterproof construction, makes it the ideal base station antenna for urban, suburban, and rural deployments where 360-degree coverage and high reliability are essential.
Key Technical Attributes and Performance
The antenna is designed specifically to leverage the high capacity and wide bandwidth available in the mid-band C-Band frequencies while addressing the inherent challenges of deploying high-frequency signals outdoors.
Optimized for the C-Band (3.7–4.2 GHz)
This frequency range is globally recognized as a core capacity layer for 5G, encompassing the widely deployed n77 and n78 bands (often referred to as 3.5 GHz spectrum). The antenna is precisely tuned for this spectrum block to ensure maximum electrical efficiency and minimal signal loss.
High Capacity: Frequencies in this range offer significantly wider channel bandwidths compared to low-band spectrums. This capacity is vital for delivering the multi-hundred Megabits per second (Mbps) speeds tat define modern 5G services.
Mid-Range Coverage: While not as far-reaching as low-band signals, the 3.7–4.2 GHz band provides an excellent balance between geographical coverage and high throughput, making it suitable for dense urban and suburban macrocell deployments.
Omnidirectional Radiation Pattern
The antenna features a true omnidirectional (360-degree) horizontal coverage pattern. This is a critical feature for base station applications:
Area Coverage: It ensures uniform signal transmission and reception in all directions around the mast or pole on which it is mounted, maximizing the number of simultaneous users or client devices that a single base station can serve.
Central Hub Functionality: It functions as a central hub, making it easy to deploy in locations where the population or client base is distributed evenly in a circular pattern around the access point.
Moderate to High Gain for Range
Despite being omnidirectional, the antenna is designed to achieve a moderate to high gain (typically ranging from 5 dBi to 10 dBi) through vertical beam compression. By flattening the radiation pattern vertically, the antenna concentrates the available power toward the horizon rather than wasting energy on the sky or ground. This technique effectively extends the communication range along the ground, compensating for the higher path loss associated with C-Band frequencies.
Rugged, Outdoor Waterproof Construction
The antenna is built for long-term, continuous operation in exposed environments. It is typically encased in a durable, UV-resistant Fiberglass Reinforced Polymer (FRP) radome and sealed to achieve a high Ingress Protection (IP) rating (e.g., IP67 or IP68). This construction provides resistance against:
Extreme weather (rain, snow, ice).
High wind loads and vibration.
UV degradation and corrosion.
This robust housing guarantees reliable performance and minimal maintenance, even in the harshest outdoor conditions.
Usage Scenarios: C-Band Base Station Deployment
The combination of omnidirectional coverage and C-Band capacity makes this antenna essential for specific high-density and FWA network infrastructures.
5G Fixed Wireless Access (FWA) Base Station
This is the primary application. The antenna is deployed on towers, rooftops, or utility poles within communities to serve a wide circle of surrounding residential and small business customers.
High-Density Service: In suburban areas, the omni pattern efficiently blankets an entire neighborhood, providing the high-capacity 3.7–4.2 GHz service to all FWA customer premise equipment (CPE) units within range.
Rapid Deployment: The simplicity of the omni setup—no aiming required—allows for faster network rollout compared to sectorized deployments.
Urban 5G Small Cell and Microcell Coverage
In dense urban cores, where macrocell coverage is difficult due to building obstructions, this antenna is used for small cell deployments on lamp posts or street furniture.
Gap Filling: The omni coverage fills in coverage gaps and boosts capacity in high-traffic areas (e.g., city squares, busy intersections) where high capacity is needed equally in all directions.
Uniform Access: It ensures that mobile users and IoT devices transitioning between different microcells maintain a smooth and consistent connection to the high-speed 5G network.
Private 5G Networks (Enterprise and Industrial)
Enterprises and industrial complexes (such as large port facilities, manufacturing campuses, or logistic centers) can use this antenna to create their own private 5G network using the C-Band spectrum.
Centralized Coverage: A single, centrally mounted omni antenna provides blanket high-capacity coverage for automated guided vehicles (AGVs), real-time video surveillance, and specialized industrial IoT sensors across a large, open area.
Simplified Infrastructure: The 360-degree reach reduces the total number of access points needed compared to sector-based systems.
The 3.7–4.2 GHz Omni Outdoor Waterproof Antenna is the critical, reliable component for network operators leveraging the C-Band spectrum to deliver comprehensive, high-speed 5G connectivity across wide geographical areas.
