Product Introduction
Full-band Coverage, Supports HD and 4K Signals
Frequency range 47-862MHz, fully supports VHF and UHF bands, compatible with digital broadcasting, HD, and 4K ultra-HD signals, easily receiving local free channels.
High-Gain Design, Indoor Signal Enhancement Powerhouse
Provides 10-12dBi gain, ensuring stable picture reception even in weak indoor environments, reducing pixelation and interruptions.
Purely Passive Design, Plug and Play, No Power Required
No external power supply required; works directly from the TV signal, energy-saving and environmentally friendly. Simple and quick installation, truly "plug and play."
High-Quality ABS Material, Beautiful and Durable
Made of ABS engineering plastic, with a simple black appearance, lightweight and sturdy, high-temperature resistant and anti-aging, suitable for various home styles.
Low VSWR and Long Cable Configuration
VSWR≤1.5 ensures efficient signal transmission. Standard 3-meter coaxial cable and IEC interface for convenient and flexible layout, adaptable to most TV locations.
Application Scenarios
●Urban Apartments and Rentals: Placed on a TV cabinet or mounted on a window, suitable for users who cannot install an outdoor antenna, receiving local HD channels.
●Student Dormitories and Bedrooms: Compact and space-saving, providing personal TV entertainment for students and family members, eliminating cable TV fees.
●Offices and Break Areas: Installed as background TV in office areas, receiving news and local programs without affecting the work environment.
●Temporary Housing and Short-Term Rentals: Suitable for hotel apartments or temporary residences, quickly setting up a TV system; portable and easy to disassemble.
●Auxiliary Reception in Areas with Good Signal: Serves as a signal source for a second TV in the home, or can be used with a signal amplifier to enhance coverage.
FAQ
Q: Does this passive antenna require an external power source?
A: No. It is a passive reception design and does not require an external power source; the signal is directly powered through the TV interface.
Q: Where is the best signal location indoors?
A: It is recommended to place it near a window or exterior wall, avoiding metal obstructions as much as possible. You can scan channels and fine-tune the position for optimal results.
Q: Does it support 4K Ultra HD TV?
A: Yes, it supports the entire 47-862MHz frequency band and is compatible with 4K, 1080p, and other high-definition formats.
Q: Does the antenna need frequent adjustment?
A: For initial installation, channel scanning and position adjustment are recommended. Due to vertical polarization, frequent adjustments are generally unnecessary.
Q: Can the cable be extended? Will it affect the signal?
A: It can be used with a high-quality coaxial extension cable, but excessive length may cause signal attenuation. It is recommended to keep the total length within 10 meters.
Q: What is VSWR? Why is it important?
A: VSWR (Voltage Standing Wave Ratio) measures the antenna-to-cable matching degree. The lower the value (e.g., ≤1.5), the less signal loss and the more stable the picture quality.
Q: Is the product compatible with all TV brands?
A: Yes, it uses a standard 75Ω impedance and IEC interface, compatible with most TVs, set-top boxes, and tuners.
