Product Introduction

Superior Signal Capture, Designed for Long Distances

Boasting an industry-leading 20-22dBi ultra-high gain, its signal reception capability far surpasses that of ordinary antennas. It effectively captures weak digital signals from tens of miles away, specifically designed to solve TV reception problems in suburban areas, rural areas, and areas with severe signal obstruction, turning previously unreceived channels into clear and stable pictures.


One-Button Convenient Power Supply, Plug and Play

Powered by a standard 5V USB, eliminating the need to find a power outlet or use a bulky adapter. Simply plug it into your TV's USB port or any mobile phone charger to power the built-in high-performance amplifier, achieving true plug-and-play functionality and completing installation in under a minute.


High-Performance Circuitry, Ensuring Lossless Signal Transmission

 A voltage standing wave ratio (VSWR) as low as 1.5 and a standard impedance of 75 ohms constitute a highly efficient power transmission system. This means that the signal received from the antenna is transmitted to your TV with minimal loss, ensuring a pixel-free and stutter-free picture, delivering a pure high-definition experience.


Rugged and Durable, Adaptable to Harsh Environments

Features an ultra-wide operating temperature range of -40°C to 85°C and is equipped with a durable black antenna cover. Its robust design is suitable not only for indoor use but also for semi-outdoor environments such as balconies and windowsills, ensuring stable operation in extreme cold or heat.


Flexible Customization to Meet Individual Installation Needs

The product comes standard with a 3-meter high-quality coaxial cable, and custom cable lengths are also available. No matter where your TV is installed, we can provide solutions to ensure the antenna is placed at the optimal signal reception point for a perfect personalized installation.


Application Scenarios

Suburban and Rural Homes: Provides a powerful signal solution for homes more than 30 miles from TV transmission towers, effectively solving the problem of weak signal due to distance.


Areas with Severe Signal Blocking: Suitable for homes surrounded by hills, dense forests, or large buildings; high gain characteristics help penetrate geographical obstacles and capture usable signals.


Users with Demanding Viewing Quality: Meets the ultimate demands of home theater enthusiasts, sports fans, and news followers for stable, uninterrupted high-definition picture quality.


Temporary high-quality viewing needs: Perfect for vacation homes, rental properties, or temporary offices, providing a high-performance temporary TV solution without compromising on outdoor antenna capabilities.


Supplementing weak signal areas in cities: Even in urban areas where signal is poor due to building structure or interference, this antenna provides ample signal headroom to ensure stable reception.


FAQ

Q: What is the maximum range of this antenna?

A: While ranges of 50+ miles are possible in ideal conditions, actual performance depends on terrain, obstacles, and broadcast power. The high 22dBi gain is specifically designed to maximize reception in long-range and weak signal scenarios.


Q: Do I need a special power adapter for it?

A: No, it uses a standard 5V USB plug. You can power it directly from your TV's USB port or any common USB wall charger/ power bank you already have.


Q: How does this high-gain antenna differ from a regular indoor antenna?

A: The key difference is signal pulling power. A regular antenna (e.g., 5-8 dBi) might work well in strong signal urban areas. Our 22dBi antenna acts like a "signal magnet," designed to lock onto distant or very weak signals that standard antennas cannot detect.


Q: Can I use this antenna outdoors?

A: Its robust build and wide temperature rating make it suitable for sheltered outdoor use (e.g., on a balcony, under an eave). However, for prolonged, direct exposure to rain and snow, a dedicated outdoor antenna is recommended.


Q: How can I get a custom cable length?

A: We offer this service to meet your specific needs. Please contact our customer service team after placing your order or via the contact form on our website to discuss your requirements.


Q: Why am I not getting all the channels I expected?

A: First, ensure you've performed a new channel scan on your TV after installation. Reception is always subject to your local environment. Using online tools like AntennaWeb.org with your address can give you a realistic expectation of available channels.
