The 350-400MHz Omni Fiberglass Waterproof Antenna is a specialized, professional-grade solution engineered for the most demanding communication tasks in the lower UHF spectrum. Frequencies in this range are unparalleled in their ability to travel vast distances, overcome geographical obstacles, and reliably penetrate dense materials—qualities that are essential for mission-critical and wide-area rural communication.
Housed in a rugged, fully sealed fiberglass radome, this antenna is built to endure permanent, long-term exposure to the harshest outdoor conditions, from coastal storms to desert heat. With its high efficiency and omni-directional pattern, it is the ideal central base station antenna for public safety, utility, and private radio networks that require stable, long-range connectivity where other frequencies fail.
Key Features and Industrial-Grade Engineering
This antenna is a powerhouse of specialized RF tuning and heavy-duty construction, designed for peak performance and minimal maintenance over its long operational life.
Specialized RF Performance
Narrow, Critical Frequency Band: Precisely tuned to the 350 MHz to 400 MHz spectrum. This is a vital band used globally for specific land mobile radio (LMR), private trunking systems, public safety, and governmental communication links that rely on superior signal propagation.
High Efficiency and Omni-Directional Coverage: The antenna provides a full 360-degree horizontal radiation pattern, making it the perfect central hub for communication networks that need to reach mobile or fixed units scattered in all directions.
Excellent Penetration Capability: The low UHF frequency is inherently superior at diffracting around large buildings and penetrating deep into forests or hilly terrain, significantly extending the reliable communication range beyond that of higher-frequency antennas.
Low VSWR and High Gain: Engineered for maximum efficiency, the antenna typically offers a competitive gain (often 6dBi or higher) and maintains a low Voltage Standing Wave Ratio (VSWR) , ensuring virtually all radio power is effectively broadcast.
Extreme Durability and Professional Interfacing
Fully Waterproof Fiberglass Radome: The central selling point is the tough, UV-stabilized Fiberglass Reinforced Plastic (FRP) casing. This material is completely waterproof and resistant to impact, corrosion, ice formation, and salt spray—guaranteeing operational integrity in every climate.
N Female Connector: Features the professional-grade, large-format N-Type Female Connector. The N-Type is the preferred choice for robust, high-power, and low-loss connections in demanding outdoor environments and ensures a high-quality interface with heavy-duty feeder cables.
Industrial Temperature Range: Designed and tested to operate reliably across extreme temperature variations .
Robust Mounting System: Includes heavy-duty pole-mounting hardware (U-bolts or clamps) engineered for stable installation on masts or towers, capable of withstanding significant wind load.
Versatile Application Scenarios
The exceptional range and stability of this low-frequency antenna make it indispensable for mission-critical communications in geographically challenging areas.
1. Public Safety and Emergency Services
Wide-Area Radio Trunking: Ideal for central repeater sites used by police, fire departments, and ambulance services to ensure seamless, clear radio communication across large counties or regions, including communication deep within buildings.
Disaster Relief Networks: Essential for establishing temporary or permanent communication infrastructure in areas with compromised cellular or internet service, relying on the proven resilience of UHF radio.
2. Utilities and Critical Infrastructure
Pipeline and Rail Monitoring: Used to provide reliable telemetry and SCADA (Supervisory Control and Data Acquisition) links to fixed sensors and remote pumping stations, often placed far from city centers. The low frequency ensures signals reach remote sites effectively.
Water Management Systems: Connecting remote reservoir and water treatment facility monitors where line-of-sight is impossible due to terrain or vegetation.
3. Specialized Private Networks
The 350-400MHz Omni Fiberglass Waterproof Antenna is the specialized, high-reliability component that secures your long-range communication links against the toughest environmental and topographical challenges.
