Before we break down what a Smart LNB is, it’s prudent to start with a clarification. Despite what you may think, Smart LNB technology isn’t proprietary to DStv. Far from it. But, of course, we’ll focus on the DStv Smart LNB. Actually, a good place to start is by explaining what exactly an LNB is and what it stands for.
LNB is an abbreviation for a Low-Noise Block down converter. This is a palm-sized device attached to a satellite dish that receives radio waves and converts them into signals your set-top box, decoder, or TV tuner can understand.
It’s interesting to note that an LNB helps maintain the overall sound and picture quality of satellite TV, regardless of your dish’s size. So, no—bigger isn’t necessarily better, depending on your needs.
DStv Smart LNB vs DStv Switch
MultiChoice retired the Multi-switch/DStv Switch in favor of the Smart LNB. The Smart LNB is capable of receiving high-band transmissions from the newly launched MultiChoice satellite.
What you should know is that the Smart LNB combines the features of the DStv Switch into a single UniCable LNB. This way, you can distribute multiple satellite signals to several decoders in your home using a single cable, simplifying installation and reducing clutter.
The Smart LNB is also essential for accessing DStv’s latest interactive services and features, including Catch Up, BoxOffice, and remote recording, as well as supporting XtraView and DStv Explora decoders.
It’s important to note, however, that if you have a single-view HD decoder and an 80cm dish, you don’t necessarily need to install a Smart LNB. The HD Decoder is a single-view decoder and can work with a standard LNB and dish.
Now for the heartbreak: DStv Smart LNB isn’t suitable for apartment complexes or similar setups. It was designed with non-commercial, single-home installations in mind. In the comfort of your own home, though, you can do wonders with it. I suppose that’s some consolation.
Smart LNB Models
From a technical standpoint, the DStv Smart LNB combines the features of a DStv Switch into a single UniCable LNB for the transmission of multiple satellite signals. DStv currently has two models of Smart LNB. The new model, LMX501, replaces the older LMX500.
DStv increased the number of user bands from 24 in the LMX500 to 30 in the new LMX501 model. To balance this, DStv reduced the UniCable outputs from 4 to 3 in the new model, and the Universal outputs from 2 to just 1.
Other Types of LNB
If you have any experience with satellite dishes, you’ll know there are various types of LNBs out there. These range from basic Single LNBs, Dual LNBs, Quad LNBs, Quattro LNBs, to UniCable LNBs.
All DStv decoders can be retrofitted with the Smart LNB. However, some XtraView combos require multi-switches with a Quad LNB to work.
Price and Where to Buy
The DStv Smart LNB retails for about $30 at DStv outlets and service centers.
