You may have seen LNB settings in your receiver menu labelled “13/18 V” and “22 kHz tone”. These are not random numbers — they are how the receiver tells the LNB which part of the satellite signal to deliver. Understanding them unlocks receiver troubleshooting. The Cable Is a Two-Way Street The coax from receiver to…
Look at any row of satellite dishes on a skyline and you will see the LNBs rotated at slightly different angles. That rotation is the LNB skew — and getting it right matters, especially if you are far east or west of the satellite. Why Skew Exists European satellites broadcast signals in horizontal and vertical…
Once you have confirmed the LNB is faulty, replacement is the easiest job in satellite TV. It takes about twenty minutes and costs less than €25. Here is how. Buy the Right Replacement Match the old LNB type: universal linear LNB for standard free-to-air; wideband LNB for Sky Q / Freesat 4K; the same number…
LNBs fail for predictable reasons. Once you know what kills them, you can choose a better one and install it in a way that survives longer. This guide covers the main failure modes. Water Ingress: The #1 Killer Rainwater creeps into an un-taped F-connector, runs along the braid, and sits in the LNB body. Once…
A suspected LNB fault is frustrating: you are up a ladder in the cold, and you need to know whether the box on the arm is actually dead before you climb down to buy a replacement. A few simple tests — with a multimeter and a satellite meter — give you the answer in minutes….
When you shop for an LNB, you will see numbers like “0.1 dB”, “0.2 dB” or “0.3 dB” splashed across the box. This is the noise figure — and it is one of the most important specs on the whole dish. Here is what it means and why a tenth of a dB matters. What…
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…
Every satellite dish ends in a small plastic box on the feed arm. That box — the LNB — is where physics meets your television. Understanding how it works makes every other satellite problem easier to diagnose. From Microwaves to L-Band A geostationary satellite broadcasts at around 10.7–12.75 GHz (Ku band). That is far too…
“LNB defekt” — the German phrase for a defective LNB — is one of the most searched satellite TV problems across central Europe. A failing LNB gives tell-tale signs, and knowing them saves you a wasted service call. This bilingual-friendly guide walks through diagnosis. Was ist ein LNB? (What Is an LNB?) Der LNB (Low…
The LNB (Low Noise Block downconverter) is the active front end of your satellite dish. It sits on the feed arm, catches the signal the dish focuses, amplifies it, and converts it to a frequency your receiver can use. When it fails, the symptoms are specific. This guide helps you recognise a faulty LNB and…
