Types of LNB: Universal, Twin, Quad, Octo and Wideband Explained
Walk into any satellite shop and the wall of LNBs is intimidating. The differences are actually simple — it all comes down to how many outputs you need and which receiver standard you have. This guide demystifies the LNB range.
Single Output LNB
One cable out, one receiver. Perfect for a single TV. Cheap and simple. If you only watch one box, this is all you need.
Twin LNB
Two independent outputs. Each output runs a full L-band to a separate receiver. Good for two TVs in different rooms. Note: each output is a separate feed — they cannot share a cable.
Quad LNB
Four outputs. The most popular for family homes. Feed four receivers, four bedrooms, or a twin-tuner PVR plus a couple of boxes.
Octo LNB
Eight outputs. For larger homes, hotels and shared systems. Beyond eight, you move to a multiswitch system.
Wideband LNB (Sky Q / Freesat 4K)
Modern Sky Q and Freesat 4K boxes use a wideband LNB, which outputs the entire band on two cables rather than switching polarity by voltage. You cannot mix a wideband LNB with a classic universal receiver — the signal format is different. Buy the one your box specifies.
Monoblock LNB
A monoblock has two horns fixed at the angle between two satellites (commonly Astra 19.2°E and Hot Bird 13°E). It uses a tiny built-in DiSEqC switch. Lets you watch two satellites from one dish without a motor.
Circular LNB
Used for American satellites (which broadcast in circular polarity rather than horizontal/vertical). Not interchangeable with European linear LNBs.
How to Choose
- One TV: single.
- Two TVs: twin.
- Family home: quad.
- Sky Q / Freesat 4K: wideband as specified.
- Two favourite satellites: monoblock.
Match the output count to the number of receivers you have today — but add two spare outputs if you can. Running extra LNB outputs is far cheaper than adding a second dish later.
