UNITEK 20m Active HDMI Cable | 4K@60Hz, 18Gbps, Active AMP Chip, Long Distance

UNITEK C11046BK: Active HDMI Cable for 4K@60Hz over 20 Metres

When your display is 20 metres away – a projector at the back of a large hall, a TV in a sprawling living room, or a digital signage screen in a commercial space – standard passive copper HDMI cables often fail to deliver a stable 4K@60Hz signal. The UNITEK C11046BK solves this problem with an Active AMP Chip that boosts the signal, ensuring a flawless picture even at this extreme length.

Active AMP Chip Technology

Unlike passive cables that rely solely on conductor thickness and shielding, the UNITEK C11046BK incorporates an Active AMP Chip (equaliser / redriver). This chip actively regenerates and amplifies the HDMI signal, compensating for attenuation caused by the long cable run. The result is a stable, artifact‑free 4K@60Hz HDR picture that rivals a short 1‑metre connection.

True 4K@60Hz Performance

The cable supports 4K Ultra HD resolution at 60Hz with a full 18Gbps bandwidth, fully HDMI 2.0 compliant. Enjoy smooth motion, vibrant HDR colours, and exceptional detail for movies, sports, gaming, and presentations. It also supports HDCP 2.2 for protected 4K content.

Triple Shielding & Gold‑Plated Connectors

Triple‑layer shielding (foil + braid + foil) protects against electromagnetic and radio‑frequency interference, which is critical for long cable runs that may pass near power cables, lighting ballasts, or other electronics. Gold‑plated connectors provide superior conductivity, resist tarnishing, and maintain a secure, corrosion‑free connection.

Advanced Audio & Video Support

• HDR (High Dynamic Range) – enhanced contrast and colour depth.

• 3D video – for compatible displays and content.

• ARC (Audio Return Channel) – sends audio from the TV back to a soundbar or AV receiver.

• CEC (Consumer Electronics Control) – control multiple devices with one remote.

• Dolby TrueHD & DTS‑HD Master Audio – lossless surround sound formats.

Ideal for Long‑Distance Setups

At 20 metres (approx. 65.6 feet) , this active cable is perfect for:

• Large home theatres with ceiling‑mounted projectors and equipment racks far from the screen.

• Conference and lecture halls where the presenter’s laptop connects at the front but the display is at the back.

• Commercial digital signage where the media player is in a remote equipment room.

• Retail, hospitality, and museum displays across large spaces.

Broad Compatibility

• 4K/HD TVs, monitors, projectors

• Gaming consoles (PS4, PS5, Xbox One, Xbox Series X/S)

• PCs and laptops with HDMI 2.0 or lower

• AV receivers, soundbars, media players

• Blu‑ray players, streaming devices

Backward compatible with HDMI 1.4 devices (1080p, 3D).

Directional Installation

The UNITEK C11046BK is a directional active cable. One end is clearly marked ”Source” (connect to your HDMI source – console, PC, media player) and the other ”Display” (connect to your TV, monitor, or projector). Installing the cable backwards will result in no signal.
