HDTV TV Antenna Signal Amplifier Booster | DVB | 75Ω | SWR ≤1.5dB | 3–5V | Low Noise | More Channels & Clearer Picture

HDTV TV Antenna Signal Amplifier Booster — DVB | 75Ω | SWR ≤1.5dB | 3–5V | Low Noise | More Channels & Clearer Picture

Boost your TV antenna signal and unlock more free-to-air channels with this HDTV TV antenna signal amplifier booster. The amplifier strengthens weakened antenna signals from distant broadcast towers — improving picture clarity, reducing pixelation and dropouts, and expanding the range of receivable channels on your TV. The low-noise design minimises signal interference introduced by the amplifier itself, preserving signal quality rather than amplifying noise alongside the signal. The 75Ω output impedance matches standard TV antenna coaxial cable for direct, compatible connection. Operates on 3–5V for low power consumption. Compatible with DVB digital broadcast frequencies.

Key Features

• More Channels — Expanded Receiving Range: The signal amplifier boosts weakened antenna signals from distant broadcast towers — expanding the range of receivable channels beyond what your antenna can pick up unaided. The number of additional channels you can receive depends on what is being broadcast in your area, your distance from broadcast towers, local terrain, surrounding buildings, and weather conditions. Check what channels are available in your area before purchasing
• Clearer Picture — Stronger Signal from Weak Sources: If your TV picture is pixelated, freezing, or dropping out due to weak signal from distant towers, the amplifier boosts the weakened signal to a level your TV can decode cleanly — restoring a stable, clear picture. Particularly effective for locations at the edge of broadcast coverage areas, in valleys or low-lying terrain, or in buildings with signal-attenuating construction materials
• Low Noise Design — Signal Quality Preserved: The low-noise amplifier design minimises the noise figure introduced by the amplifier itself — boosting the antenna signal without significantly amplifying background noise alongside it. A low noise figure is critical for antenna amplifiers: a high-noise amplifier can degrade picture quality even while boosting signal strength, while a low-noise amplifier improves both signal strength and picture clarity
• 75Ω Output Impedance — Standard Coaxial Compatible: The 75Ω output impedance matches the standard impedance of TV antenna coaxial cable — ensuring a compatible, low-reflection connection between the amplifier and your TV or set-top box. The standing wave ratio (SWR) of ≤1.5dB indicates a well-matched impedance connection with minimal signal reflection loss
• DVB Compatible — Digital Broadcast Frequencies: Compatible with DVB (Digital Video Broadcasting) digital broadcast frequencies — the standard used for free-to-air digital TV in Europe, Australia, Asia, Africa, and many other regions. Verify DVB-T, DVB-T2, or DVB-C compatibility with your specific broadcast standard and supplier before purchasing
• 3–5V Low Power — Easy Installation: The 3–5V operating voltage enables low power consumption and easy installation — typically powered via a USB port, USB adapter, or the TV’s own USB power output without requiring a separate power supply. The compact, lightweight 70g body installs easily inline on your existing antenna coaxial cable run

⚠️ Note: Select your preferred variant (D1 / D2) before adding to cart — verify the exact difference between D1 and D2 variants with supplier (connector type, cable length, or feature difference). The number of channels receivable depends entirely on your local broadcast coverage — this amplifier boosts existing signals but cannot create channels that are not broadcast in your area. Verify DVB standard compatibility (DVB-T / DVB-T2 / DVB-C / DVB-S) with supplier. Verify power supply method (USB / inline power injector) with supplier. Not suitable for use with cable TV or satellite TV systems.
