I recommend using a "universal" LNB, because they can receive the whole Ku band and have a better noise figure.

I would like to change to Ku band lnb. What type of Ku lnb do I need? The dish is pointed to Intelsat at 180° E Thank you Regards Gabriel Chingue Tue, 07 Nov 2017 13:04:18 +1300 gabriel chingue http://www.hdrlab.org.nz/blog/tips-for-aligning-satellite-dishes/#PageComment_3467 http://www.hdrlab.org.nz/blog/tips-for-aligning-satellite-dishes/#PageComment_2034 @Rajesh Actually, you might want to check whether your LNB can receive the frequencies that the new satellite's TV signals are on. I have a "universal" LNB that can receive the whole Ku band range, but other LNBs can only receive half.

There are two possible reasons why you're not receiving from the new satellite: - You haven't moved your dish to point to the new satellite; and/or - You haven't set your satellite receiver to use the new transponder frequencies and symbol rates (the chances are that they will be different from those on the old satellite). In both cases you'll need to get the new details from your dish TV company.

Recently my dish tv company has shifted to another satellite. I can get the signals at old satellite but not at new one. Can it be because of LNB?

The "black'n'white with no sound" issue sounds like your satellite receiver is outputting the wrong signal encoding for your TV (e.g., NTSC instead of PAL-B/G, which is the TV standard that New Zealand uses). Some TVs can handle multiple signal encodings, but some are not. I recommend looking in the satellite receiver's settings. You may have accidentally changed the output settings.

Because of your tip I've now officially established my LNB works - and I've found a signal - and its the right one - I can see Maori TV and Prime but not Parliament TV because the lazy beggars aren't at work. But it's all in black'n'white with no sound, so still working on it.

I'll give that a go. To add to your tips: I also wasn't sure if my satellite finder was working because I didn't know what was supposed to happen (nothing happened) when it received power - were lights supposed to come on or what? I ended up plugging it straight into the receiver using the short piece of coaxial cable and lights did indeed come on & it made a buzzy noise, so I was able to establish that it did work and the problem was that I previously didn't have it screwed into the cable properly.

The only thing that I can suggest is to double-check everything that you have done right from the beginning. Make sure that the LNB is working using the procedure outlined in this article.
