Product Introduction
Full-band high-gain coverage, one unit compatible with all channels
Fully supports the 47-862MHz VHF/UHF bands, providing 8-18dBi intelligent gain, ensuring stable reception of both local VHF channels and long-distance UHF signals.
Enhanced Yagi structure, professional directional reception
Utilizing an optimized Yagi antenna design, the 780mm extended structure combined with precision vibrator arrangement provides strong directionality, effectively eliminating interference and improving signal reception accuracy by 40%.
Wide-band high-performance design
While maintaining full-band coverage, it achieves up to 18dBi gain in the UHF band and an optimized 8dBi gain in the VHF band, meeting the professional reception needs of different frequency bands.
Rugged outdoor professional structure
Aircraft-grade aluminum alloy main beam combined with UV-resistant engineering plastic components, special anti-corrosion surface treatment, and professional packaging (785×335×565mm) ensures safe transportation.
High-Efficiency Transmission System
VSWR≤1.5 ultra-low VSWR, 75Ω standard impedance, F-type professional interface, ensuring optimized signal transmission efficiency across the entire VHF to UHF band.
Application Scenarios
Full-Band Signal Reception Area: Specifically designed for areas requiring simultaneous VHF and UHF channel reception, solving all channel reception needs with a single unit.
Ultra-Long Distance Directional Reception: Ideal for extremely remote areas more than 70 kilometers from signal towers, with 18dBi high gain breaking through traditional reception limits.
Complex Electromagnetic Environments: Accurate directional reception in densely populated urban signal areas, effectively eliminating interference from other signals.
Professional Communication Systems: Full-band signal receiving equipment for broadcasting, telecommunications, and emergency communication systems.
Special Terrain Applications: Optimized directional signal reception in mountainous areas, coastal areas, and other regions with severe multipath interference.
FAQ
Q: What are the main differences between GL923 and GL922?
A: GL923 expands to full-band coverage of 47-862MHz, increases gain to 8-18dBi, and increases length to 780mm, resulting in a comprehensive performance improvement.
Q: How to achieve optimal reception across different frequency bands?
A: It is recommended to scan VHF and UHF channels separately, fine-tune the antenna direction to find the best position that covers all channels, or use a rotator with preset positions.
Q: Is high directional accuracy required during installation?
A: Yagi antennas are quite sensitive to direction. It is recommended to use a signal strength meter for precise calibration. An error within ±5 degrees will yield the best results.
Q: How corrosion resistant is the product in coastal areas?
A: It undergoes professional anti-salt spray corrosion treatment and is suitable for use in coastal areas. However, it is recommended to perform a visual inspection and cleaning maintenance annually.
Q: Can it be used with a signal amplifier?
A: Yes, it is recommended to use a full-band signal amplifier to avoid overloading a single frequency band and affecting the reception of other channels.
Q: How resistant is the product to hail?
A: The aluminum alloy vibrator can withstand normal hail weather, but in areas prone to severe hail, it is recommended to install a protective cover.
