Product Introduction
Enhanced Yagi Directional Design for Precise Signal Acquisition
Utilizing an optimized Yagi antenna structure, the 12-15dBi gain provides superior directivity and signal acquisition capabilities, accurately aligning with the signal source and effectively eliminating multipath interference.
Top-Tier Long-Distance Reception Performance
Compared to its predecessor, the gain has been increased to 15dBi. Combined with a precision-designed director and reflector, it performs exceptionally well in ultra-long-distance signal reception scenarios.
Professional-Grade Structural Engineering Design
The aerospace-grade aluminum alloy main beam, coupled with precision-machined vibrator units, ensures a robust and stable structure. A special anti-corrosion treatment ensures long-term reliable operation in harsh outdoor environments.
High-Efficiency Signal Transmission System
VSWR≤1.5 ultra-low VSWR design, perfectly matched 75Ω standard impedance, and a professional F-type interface ensure maximum signal transmission efficiency and a clean, interference-free image.
Optimized Packaging and Installation Design
The compact packaging design (765×315×545mm) and weight of only 8.5kg facilitate transportation and installation while maintaining professional-grade performance.
Application Scenarios
* Ultra-long Distance Signal Reception: Specifically designed for extremely remote areas more than 60 kilometers from signal towers, breaking through traditional reception limits.
* Signal Acquisition in Complex Terrain:Directional signal reception in mountainous, hilly, and other complex terrain areas, accurately targeting effective signal sources.
* Professional Communication System Integration: Core receiving equipment for telecom base stations and emergency communication systems, providing reliable directional signal reception.
* Commercial Multi-User Systems:Professional-grade signal receiving front-end solutions for hotel, resort, and community television systems.
*Special Application Scenarios:Directional signal reception needs in professional fields such as scientific research monitoring and remote monitoring.
FAQ
Q: What are the improvements of the GL922 compared to its predecessor?
A: The GL922's gain has been increased to 12-15dBi, and its structure has been further optimized, resulting in a significant improvement in long-distance reception performance.
Q: How to accurately align the signal during installation?
A:It is recommended to use a signal strength meter for positioning. Use the television signal scanning function to fine-tune to the direction of the strongest signal before firmly fixing it in place.
Q:How stable is it in windy areas?
A: Utilizing a reinforced aluminum alloy structure and precision counterweight design, it boasts excellent wind resistance. However, in typhoon-prone areas, it is recommended to use a professional reinforced bracket.
Q: Can it receive TV signals from multiple directions?
A: The Yagi antenna is a highly directional antenna, optimized for single-direction reception. For multi-directional signal reception, it is recommended to use it with a rotator.
Q: What are the specific requirements for installation height?
A: A height of 5-15 meters is recommended, depending on the surrounding terrain and obstacles. Generally, higher installations result in better reception.
Q: Does the product include all necessary installation accessories?
A: Standard mounting holes are included. Please select specific mounting brackets and accessories based on your actual installation environment.
Q: Is special protection required during thunderstorms?
A: It is strongly recommended to install professional lightning protection devices in areas prone to thunderstorms to protect equipment and ensure safe operation.
