Product Introduction
1.Enhanced Signal Gain (10-12 dBi)
Provides 10-12 dBi high gain, significantly improving signal reception sensitivity and ensuring stable reception of HD channels even in remote or weak signal areas, delivering clear and smooth picture quality.
2.Precise UHF Band Coverage (470-862 MHz)
Optimized for the UHF band, covering 470-862 MHz, perfectly supporting digital TV and HD broadcasting, compatible with 4K ultra-high-definition signals, bringing an immersive viewing experience.
3.Superior Materials and Structural Design (ABS+PVC)
Made of ABS+PVC composite material, lightweight and durable, UV-resistant and corrosion-resistant, suitable for long-term indoor and outdoor use, adaptable to various installation environments.
4.High-Efficiency Signal Transmission (VSWR ≤1.5, 75Ω)
Voltage Standing Wave Ratio ≤1.5, combined with a standard 75Ω impedance, achieves high-efficiency signal transmission, minimizing loss and ensuring a pure and stable signal.
5.Wide Applicability and Easy Installation (IEC Interface, 3-meter Cable)
Standard configuration includes a 3-meter coaxial cable and an IEC interface. Plug and play, compatible with most TVs and receivers. Simple installation, no additional tools required.
Application Scenarios
●Urban High-Rise Residential Buildings:Install on balconies or near windows for effective UHF digital signal reception, avoiding building obstruction.
●Suburban and Rural Homes:High gain solves the problem of weak signals at long distances, replacing expensive cable TV services.
●Temporary Offices or Shops:Quickly set up a TV signal system; economical and practical, suitable for meeting rooms, reception areas, etc.
●Outdoor Mobile Applications: Portable to RVs and campsites; weather-resistant design adapts to temperature changes, allowing you to watch programs anytime, anywhere.
●Signal Enhancement Repeater: Can be used with a signal amplifier as a repeater antenna to improve the overall TV network coverage.
FAQ
Q: Does this antenna support 4K Ultra HD TV?
A: Yes, its UHF band covers 470-862 MHz, fully supporting 4K and all lower HD formats.
Q: Can the antenna be used in rainy or low-temperature environments?
A: Yes. The product operates in temperatures ranging from -40°C to 85°C. The ABS+PVC material provides excellent waterproof and cold-resistant properties.
Q: Does the antenna need to be adjusted during installation?
A: It is recommended to scan channels and fine-tune the antenna direction during initial installation to obtain optimal signal strength. The vertical polarization design simplifies the alignment process.
Q: Is the antenna suitable for older televisions?
A: Yes. Simply connect it to the television via the IEC interface. If the television does not have the corresponding interface, an adapter can be used.
Q: What does a gain of 10-12 dBi mean?
A: This indicates the antenna's signal reception capability. The higher the dBi value, the stronger the reception capability, especially suitable for long distances or areas with weak signals.
Q: Can the cable length be extended?
A: The standard configuration is 3 meters. A high-quality coaxial extension cable can be used, but excessive length may cause signal attenuation; it is recommended to shorten the connection distance as much as possible.
