Product Introduction
Precise Narrow Band Optimization for More Focused Signal Reception
Deeply optimized for the 470-738MHz UHF core frequency band, eliminating interference from other frequency bands and providing stronger and more stable signal reception performance within this specific frequency range.
Intelligent Dual Power Supply Design for More Flexible Usage Scenarios
Innovatively adopts IEC+USB dual-interface power supply, allowing direct power from a TV's USB port or a power adapter, meeting the needs of different installation environments and users.
High-Performance Signal Amplification, Expert in Weak Signal Enhancement
Offers 22-26dBi high gain, equipped with a professional-grade low-noise amplifier, specifically enhancing weak signals in the 470-738MHz frequency band, improving reception performance by 3 times compared to ordinary antennas.
Compact Design for Space Saving and Aesthetics Made of high-strength ABS material, the compact and lightweight structure, along with the minimalist black appearance, easily blends into various home environments, saving space and looking stylish.
Wide Operating Temperature Range for Extreme Environments
Operating within a temperature range of -40℃ to 85℃, maintaining stable performance in both frigid attics and hot garages, ensuring reliable operation around the clock.
Application Scenarios
●Specific Frequency Band Signal Areas: Specifically designed for areas broadcasting in the 470-738MHz frequency band, providing a precisely optimized signal reception solution.
●Compact Urban Living Spaces: The compact design is suitable for apartments, dormitories, and other environments with limited space; dual power supply options increase installation flexibility.
●Weak Suburban Areas: Provides professional-grade signal enhancement for suburban users with insufficient UHF signal coverage, improving the viewing experience.
●Temporary Office Spaces: Suitable for offices, shops, and other locations requiring rapid TV signal deployment; USB power supply simplifies the installation process.
●Special Climate Environments: Wide temperature range design suitable for installation in non-constant temperature spaces, such as attics, garages, and basements.
FAQ
Q: Why choose the 470-738MHz specific frequency band?
A: This is the core UHF band for digital TV broadcasting; focused optimization provides better reception and avoids wasting resources in a full-band design.
Q: Which is better, USB power supply or power adapter power supply?
A: Signal performance is the same. USB power supply is more convenient, while power adapter power supply is more stable. It is recommended to use the power adapter in areas with extremely weak signals.
Q: Will it overload in areas with strong signals?
A: No. The product features automatic gain control, which automatically adjusts the amplification factor based on signal strength to prevent overload from strong signals.
Q: What are some installation precautions?
A: It is recommended to place it near a window or exterior wall, away from metal objects. After initial installation, please perform a channel scan and fine-tune the position for optimal reception.
Q: What are the product dimensions? Does it take up a lot of space?
A: It features a compact design. Please refer to the product specifications for specific dimensions. It saves more space compared to traditional antennas.
Q: Can I connect both the USB port and the power adapter simultaneously?
A: It is not recommended to connect them simultaneously. The product is designed to operate on a single power source; simultaneous connection may cause device malfunction.
