Product Introduction

1.Superior Gain, Conquering Long Distances and Weak Signals

Boasting an astonishing 20-22dBi gain, far exceeding ordinary indoor antennas, it effectively captures weak TV signals from tens of miles away, specifically designed to solve reception problems in suburban areas, rural areas, and areas with severe signal blockage.


2.Adjustable Voltage Power Supply, Intelligent Signal Strength Optimization

The innovative 5V-12V adjustable voltage design allows you to flexibly adjust amplifier power according to signal strength. Increase the voltage when the signal is weak to enhance reception, and decrease it when the signal is strong to avoid overload, achieving optimal picture quality.


3.Wide Band Compatibility and Superior Performance

Covering the entire 470-862MHz band, ensuring perfect reception of all digital HD channels. A low VSWR (Voltage Standing Wave Ratio) of 1.5 ensures high signal transmission efficiency, converting more signal energy into a clear and stable picture.


4.Rugged and Durable, Adaptable to Harsh Environments

Operating in a wide temperature range of -40℃ to 85℃, and equipped with a weatherproof black antenna cover. This means it can be used not only indoors but also stably in semi-outdoor environments such as balconies and windowsills, adapting to various harsh weather conditions.


5.Customizable Cables and Convenient Connections: In addition to the standard 3-meter cable, custom cable lengths are supported to meet the flexible wiring needs of different installation locations. It comes standard with an F-interface and USB power supply, compatible with most modern TVs, offering plug-and-play functionality and incredibly simple installation.


Application Scenarios:

Suburban and Outlying Residences: Solves problems of weak signals, limited channels, or choppy picture quality caused by distance from TV towers.

Rural and Remote Homes: Provides users with a simple and effective free viewing solution as an alternative or supplement to large outdoor antennas.

Apartments and Villas with Signal Obstruction: For residences blocked by tall buildings or natural environments (such as mountains or forests), its high gain characteristics help penetrate obstacles and capture reflected signals.

Temporary Housing and Holiday Homes: Easy to install and carry, it allows for the rapid setup of a high-quality TV reception system for rental properties, dormitories, or weekend getaways.

For users with extreme image quality demands: Designed for those who cut cables and enjoy high-definition video with uncompressed resolution, this antenna offers superior reception performance compared to ordinary antennas.


FAQ

Q: How far away can this antenna receive signals?

A: The range can be 50+ miles depending on terrain and obstacles. The high 22dBi gain is designed for long-range reception, but actual results vary. Check online for transmitter locations in your area.


Q: What is the advantage of adjustable 5V-12V power?

A: It allows you to optimize performance. Use a higher voltage (e.g., 12V) for very weak signals to boost amplification, and a lower voltage (e.g., 5V) for stronger signals to prevent over-amplification which can cause pixelation.


Q: Do I need a special power adapter?

A: It uses a standard USB connection. You can plug it into a TV USB port or any wall charger. To use the adjustable voltage feature, you will need a compatible adjustable USB power supply or a power adapter with variable voltage outputs.


Q: Can this antenna be used outdoors?

A: Its robust design with a wide operating temperature range makes it suitable for sheltered outdoor placements like balconies or under eaves. However, for full, prolonged exposure to rain, a fully waterproof outdoor model is recommended.


Q: How do I customize the cable length?

A: Please contact us directly after placing your order or through our customer service channel to discuss your specific cable length requirements.


Q: Will this work if I already have a weak signal?

A: Yes! This is exactly what this antenna is designed for. The high gain and amplification are specifically intended to pull in and strengthen weak signals that standard antennas cannot.
