The 400-425MHz N Female Fiberglass Antenna is engineered for high-reliability communication in the lower Ultra-High Frequency (UHF) band. Frequencies in this range are prized for their exceptional ability to penetrate heavy foliage, traverse hills, and reliably pass through building materials—qualities that are non-negotiable for critical communications and challenging geographical deployments.
Housed in an incredibly durable fiberglass radome, this antenna is designed for permanent, long-term outdoor installation, resisting the harshest elements from high winds to corrosive salt spray. Whether you are setting up a specialized private mobile radio (PMR) network, a wide-area telemetry system, or a crucial governmental link, this antenna provides the stable, long-range connectivity required for mission success.
Key Features and Professional Construction
This antenna is a blend of precision RF tuning and industrial-grade mechanical design, ensuring both superior performance and extreme longevity.
Optimized UHF RF Performance
Specialized Frequency Band: Precisely tuned to the 400 MHz to 425 MHz spectrum. This is a critical band used globally for various specialized applications, including private land mobile radio (LMR), licensed telemetry, amateur radio, and certain military/government communications.
High-Gain Options: Available in various gain levels (typically 5dBi to 9dBi) to maximize the Effective Radiated Power (ERP). This focuses signal energy towards the horizon, significantly extending the communication range and link budget compared to stock antennas.
Omni-Directional Pattern: Provides uniform signal radiation across a 360-degree horizontal plane. This makes it an ideal central access point or base station antenna that needs to communicate with mobile or fixed end-points scattered in all directions.
Low VSWR and High Efficiency: Engineered for superior electrical efficiency, maintaining a low Voltage Standing Wave Ratio (VSWR) . This ensures that virtually all power from your radio is radiated effectively, maximizing your precious communication range.
Industrial-Grade Durability
Fiberglass (FRP) Radome: The tough, UV-stabilized Fiberglass Reinforced Plastic (FRP) casing provides a completely sealed environment for the antenna element. This material offers superior resistance to UV damage, impact, and corrosion.
All-Weather Reliability: Designed to operate flawlessly in extreme conditions, including wide temperature fluctuations, heavy rain, snow, and high wind loads, ensuring year-round, uninterrupted service.
N Female Connector: Features the professional-grade, weatherproof N-Type Female Connector. The N-Type is known for its ruggedness and superior performance at UHF frequencies, providing a low-loss, high-integrity connection with quality feeder cables.
Secure Mounting: Includes heavy-duty mounting hardware (such as U-bolts or pole clamps) built to secure the antenna rigidly against strong winds and environmental vibration.
Versatile Application Scenarios
The low-frequency penetration and durability of this antenna make it indispensable for critical and geographically challenging communication tasks.
1. Private Radio and Land Mobile Radio (LMR)
Commercial Fleet Communication: Establishing long-range communication links for transportation companies, construction sites, or utility maintenance crews operating across large, difficult-to-cover territories.
Government and Public Service: Used for reliable communications in non-urban areas where the 400 MHz band's ability to penetrate hills and dense woods is vital for maintaining contact between remote teams.
2. Long-Range Telemetry and SCADA
Utility Monitoring: Ideal for connecting SCADA (Supervisory Control and Data Acquisition) systems to remote endpoints, such as pipeline monitors, water treatment plants, or power grid control stations, ensuring data packets reliably travel long distances.
Environmental Sensing: Used in rugged, remote locations for real-time data collection from environmental sensors, weather stations, and seismic monitors where the signal must contend with heavy terrain and foliage.
3. Specialized IoT and Data Links
Wide-Area IoT: Deploying private networks for specialized industrial IoT applications that require long-range, low-data-rate connectivity over many kilometers, leveraging the superior propagation characteristics of the lower UHF band.
By investing in the 400-425MHz N Female Fiberglass Antenna, you are choosing a powerful, robust, and specialized solution designed to deliver stable, long-range communication where standard antennas simply cannot perform.
