How to Connect Multiple TVs to One Decoder

If you have one satellite or digital decoder but want to watch television in more than one room, you don't necessarily need a separate decoder for every screen. Depending on your budget and how much flexibility you want, there are a few reliable ways to share a single decoder across multiple TVs.

Method 1: RF Splitter and Coaxial Cabling (Same Channel Everywhere)

The simplest and cheapest option is to distribute the decoder's signal through an RF (radio frequency) splitter connected to coaxial cable running to each TV.

What you need: an RF modulator (some decoders have this output built in), an RF/coaxial splitter, coaxial cable, and connectors for each room.

Steps:

1. Connect the decoder's RF or antenna output to the input of the splitter.
2. Run coaxial cable from each splitter output to the antenna/RF input on every TV.
3. Tune each TV to the correct channel number the decoder broadcasts on (usually a specific UHF channel, set in the decoder's RF output settings).

Limitation: every TV will show exactly the same channel at the same time, since they're all just receiving the same signal. This works well for shared spaces like a lounge and an adjoining bar area, but not if different family members want to watch different channels.

Method 2: HDMI/AV Splitter (Same Channel, Better Picture Quality)

If your rooms aren't too far apart, an HDMI splitter can mirror the decoder's output to multiple TVs with better picture quality than the RF method. You'll need an HDMI splitter box and HDMI cables running to each TV. Like the RF splitter method, all screens display the same content simultaneously.

Method 3: Multi-Room Decoder Technology (Different Channels on Each TV)

For real flexibility — each TV showing a different channel, controlled by its own remote — you need a decoder that supports multi-room or multi-TV technology, such as DStv's Xtraview or GOtv's multi-TV feature.

How it works: Your main decoder acts as the hub. You connect a second (and sometimes third) decoder unit in another room, and link them using either:

• A dedicated multi-room cable running between the decoders, or
• A wireless multi-room connector kit, which uses your home's electrical wiring or Wi-Fi to link the units without running new cable.

Steps:

1. Confirm your main decoder model supports multi-room viewing and that your subscription package includes the Xtraview or multi-TV add-on.
2. Install the secondary decoder in the second room and connect it to that TV as normal.
3. Link the two decoders using the multi-room cable or wireless kit as per the manufacturer's pairing instructions.
4. Activate the multi-room service on your account, then each decoder can independently select channels from the shared subscription.

Which Method Should You Choose?

• Same content, tight budget: RF or HDMI splitter.
• Different content per room: multi-room decoder setup.
• Long cable runs or many rooms: consider professional installation to route cabling neatly and avoid signal loss.

A Final Tip

Signal loss increases with cable length and the number of splitter outputs, so keep runs as short as possible and use quality shielded cable. If you're unsure which decoder model or cabling your home needs, it's worth having a technician assess your setup — a wrongly wired splitter can weaken the signal on every TV, not just the extra ones.
