28dBi gain 47-862MHz Outdoor High Gain HDTV Antenna

Product Introduction

1.Extremely Strong Long-Range Signal Acquisition:Boasting an exceptional gain of up to 28dBi, it powerfully amplifies weak signals, specifically designed for areas extremely far from TV transmission towers (such as remote rural areas and mountainous regions) or where signal obstruction is severe. It effectively receives TV programs from tens of kilometers away.

2.Superior Anti-Interference and Pure Image Quality:With a front-to-back ratio ≥24dB, it effectively suppresses environmental interference and signal reflections from behind the antenna, accurately locking onto the target transmission tower, significantly reducing image ghosting and snow, and ensuring a clear and stable received image.

3.Full-Band Coverage, One-Time Solution:Fully covers the 47-862MHz ultra-wide frequency band, compatible with all digital high-definition (HDTV/4K) and analog TV channels in VHF (low frequency) and UHF (high frequency), meeting viewing needs for many years to come without the need to replace equipment due to channel changes.

4.High-Efficiency Signal Transmission with Extremely Low Loss:With a voltage standing wave ratio (VSWR) ≤1.5, it indicates near-perfect impedance matching between the antenna and the feeder system, maximizing the transmission of captured signal energy to the TV set and reducing internal losses—a fundamental guarantee of high-definition image quality.

5.Professional Outdoor-Grade Rugged Construction: Designed to withstand harsh outdoor environments, its robust structure is wind and rain resistant. A maximum 50W power input ensures stable operation even under high-intensity signal conditions, making it a reliable long-term investment for free HDTV.

Application Scenarios

●Remote Rural and Mountainous Families: Solves the problem of complete lack of reception or extremely poor signal due to distance from TV towers.

●Suburban Areas with Severe Signal Obstruction: Penetrates buildings, hills, and other obstacles to improve viewing quality.

●Users Seeking the Highest Reception Performance: Designed for HD enthusiasts who want to receive the farthest and most channels.

●Farms, Ranches, or Remote Workstations: Provides television entertainment and information sources for isolated buildings lacking cable/satellite service.

●As a Receiver in Signal Distribution Systems: Connects multiple TVs or cable TV headend systems in small communities.

FAQ

Q: How far can a 28dBi gain actually receive signals?

A: Under ideal line-of-sight (unobstructed) conditions, theoretically, signals can be received up to 80 kilometers or even further. The actual distance is greatly affected by terrain, tower power, and installation height; it is recommended to assess this using a local signal map.

Q: Is installation complicated? Are specialized tools required?

A: Installation requires a mounting bracket (usually included) and a coaxial cable connection. Most importantly, the antenna must be aligned with the tower, which may require basic tools such as a wrench. For rooftop installations, it is recommended that this be done by a professional for safety.

Q: Is an amplifier necessary?

A: Usually not. The 28dBi antenna gain is already very strong. Adding an amplifier may cause distortion due to excessive signal strength, or even interfere with the system. A low-noise line amplifier should only be considered when using extra-long feeders (>50 meters).

Q: Can it receive satellite TV or connect to cable TV?

A: No. This is an antenna specifically designed for receiving over-the-air (OTA) broadcast television signals. Satellite TV requires a parabolic satellite dish and a dedicated tuner; cable TV requires a direct connection to the service provider's line.

Q: Does the package include all the necessary installation accessories? 

A: Typically includes the antenna body, mounting bracket, and U-bolts. Mounting pole, sufficient length of high-quality 75-ohm coaxial cable, and waterproof connectors need to be purchased separately depending on your specific installation plan.
