Product Introduction

1.Intelligent Dual Power Supply Design for More Flexible Use Scenarios

Innovatively adopting an IEC+USB dual-interface power supply design, it can be powered directly from the TV's USB port or using a power adapter, meeting the needs of different installation environments.


2.Professional-Grade Signal Amplification, a Savior in Weak Signal Areas

Equipped with a high-performance signal amplifier, providing 20-26dBi intelligent gain, it automatically identifies and enhances weak signals, effectively solving reception problems in remote areas and signal dead zones.


3.Full-Band Coverage, Supports the Latest TV Formats

Completely covers the 47-862MHz VHF/UHF bands, fully compatible with all digital TV formats such as 4K Ultra HD and 1080p Full HD, with a future-proof design.


4.Military-Grade Material Structure, Enhanced Durability

Utilizing an ABS+steel composite structure, it maintains lightweight while providing excellent structural strength, resisting drops and shocks, and boasting a lifespan far exceeding that of ordinary plastic antennas.


5.Wide Operating Temperature Range, Adaptable to Extreme Environments

With an operating temperature range of -40℃ to 85℃, it maintains stable performance in both frigid winters and scorching summers, making it suitable for installation in non-constant temperature spaces such as attics and garages.

Application Scenarios

●Urban Apartment Signal Dead Zones: Specifically designed to solve weak signal problems in lower floors of high-rise buildings and areas facing away from cell towers, requiring no outdoor installation.

●Ideal Choice for Renters: USB power supply avoids circuit modifications; 3-meter cable provides flexibility and is portable during moves.

●Home Theater Upgrade: Provides a stable and powerful signal source for 4K/8K Ultra HD TVs, fully unleashing the potential of high-end TV picture quality.

●Temporary Office and Commercial Spaces: Quickly deployable in shops, offices, and hotel rooms; dual power supply options adapt to various decoration situations.

●Emergency Communication Backup System: Serves as a backup signal reception solution during natural disasters or network outages; wide-temperature design ensures normal operation under extreme weather conditions.

FAQ

Q: Which is better, USB power or power adapter power?

A: Both methods provide the same signal strength. USB power is more convenient, while power adapter power is more stable. We recommend using the power adapter in areas with extremely weak signal.


Q: Does the antenna need to be pointed in a specific direction?

A: The vertical polarization design simplifies the installation process. We recommend performing a channel scan during initial installation and making slight adjustments to the optimal signal position.


Q: Will it overload in urban areas with strong signals?

A: No. The product has Automatic Gain Control (AGC) which automatically adjusts the amplification factor according to signal strength to avoid overloading strong signals.


Q: Can I connect both the TV's USB port and the power adapter simultaneously?

A: We do not recommend connecting them simultaneously. The product is designed to operate on a single power source; simultaneous connection may cause device malfunction.


Q: What is the purpose of the steel components on the antenna surface?

A: The internal steel frame provides structural support, ensuring the antenna does not deform during long-term use and does not affect signal reception performance.


Q: Is the product suitable for older CRT TVs? 

A: As long as the TV has an IEC interface or can be connected via an adapter, and supports digital signal reception, it can be used.
