【 Scene Entry: The Double-Edged Sword of Drones】 When the drones, with their dazzling light shows, illuminate the night sky and precisely deliver relief supplies to the isolated islands, we are amazed by the boundless possibilities brought by technology. However, on the other hand, the "unauthorized flight", "random flight" and malicious interference of drones are like the sword of Damocles hanging over our heads: Privacy infringement: Drones can easily transform into "air spies" to spy on corporate secrets, military restricted areas and personal lives. Public safety threats: In sensitive areas such as airports and large-scale events, unauthorized drones may cause catastrophic consequences such as collisions and panic among people. Information interference and hijacking: Out-of-control or malicious signals can interfere with the normal communication of drones and even lead to their hijacking, turning them from tools into weapons. Traditional response methods, such as signal jamming guns, often have single means, limited coverage, and are prone to harming innocent communications in complex environments, treating the symptoms rather than the root cause. 【The solution: From "Passive Defense" to "Active Control"】 The key to dealing with the threat of drones lies in absolute control over their communication links. What you need is not a crude "blocking", but a more powerful, precise and intelligent "connection" and "management". We bring you the ultimate solution 【Product Debut: Technical Core, Advantages Fully Displayed】 Directional + omnidirectional multi-band combined MIMO antenna array This is a revolutionary product specially designed for high-end unmanned aerial vehicle communication, measurement and control, and countermeasure systems. With its outstanding performance, it builds an impregnable air signal defense line for you. 360° seamless coverage: A 6-sided high-gain (7dbi) 2.4G antenna circular array forms a powerful "omnidirectional signal fortress", completely eliminating communication blind spots in the horizontal direction and ensuring that the target unmanned aerial vehicle is always within the monitoring and connection range. Top-mounted sky dome, vertical enhancement: The unique 2.4G 7dbi directional antenna at the top, like a "sky eye", achieves precise enhanced coverage of the airspace, effectively addressing the signal challenges when drones fly or hover at high altitudes. Multi-band intelligent coordination: Integrated 2.4G and 5.8G omnidirectional antennas (gain 3dbi), dual-band concurrent operation, intelligent switching. Not only can it be compatible with the vast majority of communication frequency bands for drones on the market, but it can also effectively avoid channel congestion and ensure the ultimate stability and ultra-low latency of instruction transmission. Performance multiplication: By adopting multi-input multi-output technology, the channel capacity and data transmission rate are significantly enhanced. This means smoother high-definition image transmission, faster control response, and stronger anti-interference ability, allowing you to handle complex electromagnetic environments with ease. From "driving away" to "managing" : It can not only effectively detect and drive away "unauthorized" drones, but also achieve stable and reliable remote takeover and guidance of authorized drones, turning threats into tools. All-round impeccable: Whether it's horizontal hovering or vertical takeoff and landing, no drone from any Angle can escape your "sharp eyes" and "control". Future-oriented compatibility: The multi-band design enables it to adapt to the constantly evolving drone communication technology, ensuring the long-term effectiveness of your investment.

An omnidirectional outdoor base station gateway fiberglass antenna is a high-performance communication component designed specifically for outdoor base stations and gateway devices. With fiberglass as its core material, it combines omnidirectional signal radiation capabilities with exceptional environmental adaptability. Serving as a critical signal bridge between base stations and terminal devices (such as mobile phones, routers, and IoT devices), it is widely used in rural communication coverage, outdoor park networking, signal enhancement in remote areas, and other scenarios, making it a core part of outdoor wireless communication systems. Working Principle: The Core Logic of Unobstructed Signal Transmission Its working principle is based on the omnidirectional radiation and reception characteristics of electromagnetic signals. The core radiating element wrapped in fiberglass can convert electrical signals output by the base station gateway into electromagnetic waves, which diffuse evenly in a 360° direction to cover a certain radius. Simultaneously, it captures signals from terminal devices in all directions, converts them back into electrical signals, and transmits them to the gateway, enabling two-way communication. The fiberglass housing not only provides insulation but also focuses signal energy to improve transmission efficiency. Combined with impedance matching technology, it reduces signal attenuation and ensures stable long-distance communication. Core Advantages: A Benchmark for Outdoor Communication Performance Superior Durability: Fiberglass material resists high temperatures (-40℃ to +85℃), corrosion, and UV radiation, withstanding harsh outdoor conditions like heavy rain, strong winds, and sandstorms. Its service life exceeds 10 years, far longer than traditional metal antennas. 2、360° Unobstructed Coverage: The omnidirectional radiation design eliminates "dead zones" common with directional antennas, covering   3、surrounding areas without angle adjustments. It is particularly suitable for communication needs in open spaces or complex terrains. 4、Low Loss & High Gain: Fiberglass’ low dielectric constant minimizes signal transmission loss. Equipped with a high-gain design (usually 8- 12dBi), it enhances signal penetration, expands coverage range, and improves connection stability in weak signal areas. 5、Easy Installation & Strong Compatibility: Lightweight (only 300-500g) with waterproof connectors, it can be directly fixed to base station brackets, roofs, or outdoor poles. Compatible with multi-band gateway devices (4G/5G, Wi-Fi, IoT), it adapts to various outdoor communication scenarios.  

1. Vehicle Navigation and Monitoring In-vehicle satellite positioning antennas are core components of navigation systems. They receive satellite signals for real-time positioning, providing drivers with services such as route planning and road condition alerts. (Common in-car navigation systems and mobile navigation apps rely on these antennas.) In industries such as freight, taxis, and ride-hailing, real-time data from positioning antennas can be used to implement functions such as vehicle dispatching, trajectory tracking, and anti-theft monitoring, improving operational efficiency and safety. 2. Intelligent Transportation Systems (ITS) Applied to autonomous vehicles, high-precision satellite positioning antennas (combined with technologies such as RTK) provide centimeter-level positioning information, assisting vehicles in sensing their surroundings, planning routes, and ensuring the accuracy of autonomous driving. In highway ETC systems and traffic flow monitoring equipment, positioning antennas help identify vehicle location and driving status, enabling intelligent toll collection and congestion warnings. 3. Navigation and Aviation Ship navigation systems receive signals from satellite positioning antennas to determine a vessel's latitude, longitude, heading, and speed, preventing loss of direction or collisions. These devices are essential for ocean voyages. In general aviation (such as small aircraft and drones), positioning antennas provide real-time location information for aircraft to ensure flight path planning and safety monitoring.

The China Outdoor Waterproof Directional Antenna, also known as the China Outdoor Waterproof Directional Antenna, is a waterproof antenna manufactured by a Chinese company. It features directional signal transmission and is waterproof. The following is a brief introduction: 1.
