Product Introduction
Flagship-Level Full-Band Performance
Completely covers the 47-862MHz VHF/UHF bands, offering industry-leading gain of 14-18dBi, maintaining excellent reception performance in both VHF and UHF bands, solving all digital TV signal reception needs with a single unit.
Precision Yagi Directional Optimization Design
850mm precision engineering structure, optimized element arrangement and spacing, strong directionality effectively eliminates multipath interference, improving reception accuracy by 60% compared to ordinary antennas, resulting in stable, snow-free images.
Professional Outdoor Durable Structure
Aerospace-grade aluminum alloy main beam combined with UV-resistant engineering plastic components, an 850mm reinforced structure ensures stability in harsh weather conditions, and professional anti-corrosion treatment ensures a long outdoor service life.
High-Efficiency Full-Band Signal Transmission
VSWR≤1.5 ultra-low VSWR, 75Ω standard impedance perfect matching, and a professional F-type interface ensure optimal signal transmission efficiency and minimize signal loss across the entire VHF to UHF band.
Compact and Lightweight Packaging Design
Optimized packaging dimensions of 765×345×530mm and a lightweight design of 8.5kg facilitate transportation and installation without sacrificing performance, significantly improving installation convenience.
Application Scenarios
Full-Band Signal Reception Area: Specifically designed for areas requiring simultaneous reception of all VHF and UHF channels, providing full coverage with a single unit.
Extremely Weak Signal Environments: Remote rural and mountainous areas more than 80 kilometers from signal towers; 18dBi high gain breaks through traditional reception limits.
Professional Communication System Integration: Signal receiving equipment for broadcast monitoring and telecommunications base stations, providing reliable full-band signal support.
Commercial Multi-User Systems: Front-end equipment for centralized TV signal distribution systems in hotels, resorts, and residential communities.
FAQ
Q: What are the key upgrades of the GL933 compared to its predecessor?
A: Gain increased to 14-18dBi, length optimized to 850mm, significantly improving reception performance across the entire frequency range, especially in weak signal environments.
Q: How to balance VHF and UHF band reception during installation?
A: We recommend scanning VHF and UHF channels separately, fine-tuning to find the optimal direction that covers all channels, or using a rotator with preset positions.
Q: How is stability guaranteed in strong wind areas?
A: Utilizing a thickened aluminum alloy main beam and optimized structural design, it offers excellent wind resistance. In typhoon-prone areas, we recommend using professional windproof supports and additional reinforcement.
Q: Is lightning protection necessary?
A: In areas prone to thunderstorms, professional lightning arresters must be installed, ensuring proper grounding to protect equipment and ensure safe operation.
Q: What is the optimal installation height range?
A: We recommend an installation height of 6-15 meters, depending on the surrounding terrain and obstacles. Lowering the height is acceptable in flat, open areas, while higher positions are recommended in densely built-up areas.
Q: Can it be used with signal amplifiers?
A: It is perfectly compatible with full-band signal amplifiers. We recommend selecting a high-quality professional-grade amplifier and paying attention to impedance matching for optimal results.
