Product Introduction
Professional VHF/UHF Band Precision Optimization
Deeply optimized for the 47-862MHz VHF/UHF band, accurately receiving digital TV signals, eliminating VHF band interference, and providing a cleaner and more stable high-definition picture experience.
High-Performance Signal Amplification Technology
Offers 25-28dBi high gain, with a built-in low-noise amplifier, effectively enhancing weak UHF signals. The receiving distance is 3 times longer than ordinary antennas, completely solving the signal dead zone problem.
High-Quality ABS Material: Lightweight and Durable
Made of high-strength ABS engineering plastic, lightweight, impact-resistant, and anti-aging, with a simple and stylish appearance that easily blends into various home décor styles.
Intelligent Automatic Gain Control
Equipped with Automatic Gain Control (AGC) circuitry, it monitors signal strength in real time and automatically adjusts the amplification factor to avoid overload of strong signals, ensuring a consistently clear and stable picture.
Global Voltage Compatibility
Supports AC 110V/220V global voltage, equipped with a safety-certified power adapter, and features comprehensive overvoltage and overcurrent protection to ensure safe and stable operation in different countries and regions.
Application Scenarios
●Urban Apartment UHF Reception: Specifically designed to solve the problem of UHF signal blockage by buildings in urban environments, suitable for users on lower floors of high-rise residential buildings.
●Dedicated Digital TV Areas: Suitable for digital TV broadcasting areas primarily using the UHF band, providing accurate reception without wasting resources.
●Suburban Weak Signal Environments: Provides professional-grade signal enhancement solutions for users in suburban and rural areas with weak UHF signal coverage.
●Commercial Multi-Room Applications: Core signal acquisition equipment for multi-room TV systems in hotels, offices, shops, etc.
●Temporary Events and Displays: Temporary TV displays at exhibitions and sales points, quickly establishing a professional TV signal reception system.
FAQ
Q: Can this antenna receive VHF channels?
A: The GL2790 is specifically optimized for the 470-862MHz UHF band. To receive VHF channels, please select a full-band antenna model.
Q: Will it overload in cities with strong signals?
A: No. The product has automatic gain control, which automatically adjusts according to signal strength to avoid overload issues in areas with strong signals.
Q: What are some installation tips?
A: We recommend placing it near a window or exterior wall, away from metal objects and electronic devices. An installation height of 1-2 meters is optimal. Please perform a channel scan before first use.
Q: How durable is the ABS material?
A: Made of high-strength ABS engineering plastic, it has passed operating temperature tests from -40℃ to 85℃, is impact-resistant and anti-aging, ensuring no deformation over long-term use.
Q: How much power does the product consume when operating?
A: Extremely low power consumption, approximately 3-5W under normal operating conditions. It is more energy-efficient than ordinary light bulbs and can be left on for extended periods without increasing electricity bills.
