For most satellite dishes, the answer is simple.
Pretty much every modern satellite dish made today is designed to receive transmissions on the Ku band of 11.7-12.7GHz.
These signals are easy to generate and many satellite LNBs are designed to accept horizontal polarization which is used throughout the world..
How do I fix my satellite dish LNB?

Can I use any LNB on my dish?
As a general rule, you can’t use an LNB unless it’s designed for the dish you have. If you use the wrong LNB, the dish will focus the signals in the wrong place and you’ll get no reception. DIRECTV and DISH have specific LNBs that are designed to pull in signals from their specific fleets of satellites.

How long should an LNB last?
Yes it is, though you’re assuming the LNB is in use 24/7. If you were to use a figure of 14 hours of use per day (0900 – 2300) it’s a lifetime of just over 714 days, or a bit less than two years.
Does LNB affect picture quality?

Satellite receivers send a low voltage charge up the coaxial cable to power the LNB, so always disconnect the power before checking an LNB. … If the casing is warped or cracked, you will need to replace the LNB, because water ingress will have damaged the electronics inside the casing.
Can a satellite dish go bad?
If you’re watching TV and all of a sudden you lose satellite signal, it’s probably not a broken LNB. … As someone who talks to a lot of DIRECTV and DISH installers, I can assure you that LNBs break all the time. The good news is that they usually break immediately, or they break after about 3-4 years.
How do I know if LNB is faulty?
Signs of a faulty LNB include missing satellite television channels, video pixelation, signal drop-out during heavy rain or the complete loss of signal. To troubleshoot an LNB, first visually check the device and then test the signal levels with a digital-satellite signal meter.
How does LNB satellite dish work?
An LNB has two important functions: it’s a low-noise amplifier, meaning that it takes the extremely weak satellite signal and amplifies it. … The big, round, “dish” part of your dish acts as a lens, focusing as much signal as possible onto the LNB. The LNB amplifies that signal and sends it down the cable.
