Product Introduction
**Professional Yagi Directional Design for Precise Signal Reception** Utilizing a classic Yagi antenna structure, it boasts strong directionality, accurately aligning with the signal source and effectively eliminating interference from other directions, delivering outstanding performance in complex signal environments.
**Top-Tier Gain Performance, Long-Distance Reception Expert** Offering 10-12dBi high gain, combined with directional reception characteristics, it increases the reception distance by 50% compared to ordinary omnidirectional antennas, specifically optimized for long-distance signal reception.
**Precision Structural Engineering for Superior Durability** Employing an aluminum alloy main beam and precision-machined vibrators, the structure is robust and stable, with a special surface treatment for corrosion resistance, ensuring long-term use in harsh outdoor environments.
**High-Efficiency Signal Transmission System** VSWR≤1.5 ultra-low standing wave ratio, perfectly matched 75Ω standard impedance, and a professional F-type connector ensure minimal signal transmission loss for cleaner image quality.
**Lightweight Professional Design** An optimized 720mm length and lightweight 8.5kg packaging ensure both performance and ease of installation and transportation, while the professional design showcases its quality.
Application Scenarios
* Ultra-long Distance Signal Reception:Specifically designed for remote areas more than 50 kilometers from signal towers, the Yagi structure breaks through reception limits.
* Directional Signal Enhancement: Precisely receives signals from a specific direction, avoiding interference from other directions.
*Professional Communication Systems: Directional signal receiving equipment for telecommunications base stations and emergency communication systems.
*Mountainous Terrain Applications: Receives reflected signals from specific directions in mountainous areas.
* Commercial Multi-System Integration: Professional-grade signal receiving front-end equipment for hotel and community television systems.
FAQ
Q:What is the difference between a Yagi antenna and a regular antenna?
A:Yagi antennas have strong directionality, accurately receiving signals from a specific direction and eliminating interference from other directions, making them suitable for long-distance directional reception.
Q: How do I determine the optimal direction during installation?
A:It is recommended to use a signal strength meter or a television signal scanning function, slowly rotating the antenna to find the direction with the strongest signal before fixing it.
Q:Does the antenna need frequent direction adjustments?
A:Once the optimal direction is determined and fixed, frequent adjustments are usually not necessary unless the location of the local signal tower changes.
Q: How wind-resistant is the product?
A: Utilizing an aluminum alloy reinforced structure, it can withstand most harsh weather conditions. However, in areas with strong winds, additional reinforcement brackets are recommended.
Q: Can it receive signals from multiple directions simultaneously?
A: The Yagi antenna is a unidirectional antenna, designed specifically for receiving signals from a single direction. For multi-directional reception, an omnidirectional antenna is recommended.
Q: What are the installation height requirements?
A: Installation at 5-10 meters above ground level is recommended. The specific height depends on the surrounding terrain and obstacles.
