A Duo LNB is a double low-noise block downconverter (LNB) developed by SES for the simultaneous reception of satellite television signals from both the Astra 23.5°E and Astra 19.2°E satellite positions.

A low-noise block downconverter (LNB) is the receiving device mounted on satellite dishes used for satellite TV reception, which collects the radio waves from the dish and converts them to a signal which is sent through a cable to the receiver inside the building.

The difference between a dual LNB and a single LNB is the number of outputs on it. A dual-line LNB has two coaxial connections, while a single-line LNB only has one. A single-line LNB can only serve one receiver at a time, and you can only view one channel at …

Dual LNB. Here the dual connections operate independently of each other, enabling you to use two receivers. Hence, a dual LNB can access different channels on different transponders, but a condition applies here is that you need to install a multi-switch to split the signal. You can enjoy flipping as many channels as you want.

A dual LNB (Low Noise Block-Down Converter) is an LNB system that features two outputs rather than one and allows satellite television subscribers to watch multiple channels on separate television sets simultaneously.

A Dual LNB will allow for two separate satellite receivers to be connected or a one satellite PVR. If you have recently upgraded to Sky Q and see that your LNB has two connections only, please be aware that this is not a dual LNB but a Sky Q wideband LNB that works very differently.

A dual LNB satellite dish brings you more programming options than a single LNB system, because a dual LNB can receive satellite signals from two different satellites at the same time. These extra channels are a bonus on your programming options, but you can only enjoy them if you install dual LNB satellites correctly.
