Swapping a Sky LNB from dual to quad
Easy DIY job or not?
My parents have just had a load of work done (by me of course) and they will need a quad LNB fitting. Is it as simple as getting the ladders off the van, swapping it and then looking on the Sky tuning menu for signal strength. Maybe a small tweak if needed (and that can only be a rotational twist of the LNB as the dish is already aiming in the right direction) and then you are done, or am I being too optimistic? -- Adam |

I put a dish up just using the built in signal strength meters once. I have swapped an LNB once without having to realign anything. If its a proper sky lnb you just set the rotation to the scale on the side, it should be the same as the existing one. |

I think that there are two possible problems: 1) The age of the existing LNB. There are at least two sizes and the newer ones don't fit the older dishes and vice-versa. You need to measure up beforehand or obtain one with adapters for both. 2) ISTR, but am less certain on this, that non-Sky LNBs can have a different "neck" so they end up further forward or back and not properly at the focal point. Again the right ones can be obtained. SteveW |

Yep, that they should have some so you can **** them. |

It's a lot easier to replace the dish at the same time. There's very little cost difference. Reasons are that the LNB bolts might be rusted up and the fact that LNB holders vary. If you do decide to use the same dish be aware that the quads are a bit heavier and the arm will settle a bit lower, so an elevation adjustment might be needed. If you change the dish simply look down on the existing one from above and line up the LNB arm against something on the ground (a bit of wood or a ruler). Then set the azimuth (left-right) of the new dish so it's the same. Then adjust the elevation (up down) for the strongest signal. Then double check the azimuth. Use a Fringe satmeter. http://cpc.farnell.com/fringe/uhf-signal/signal-finder-uk-tv/dp/AP02834?mckv=sUhPm3bzh_dc|pcrid|72935509697|kword| |match||plid|&CMP=KNC-GUK-CPC-GEN-SHOPPING-FRINGE-Aerial__Satellite_Equipment-AP02834 Or google CPC satellite meter or look on the Fringe website. They're about £20. They are far better than other makes. Some LNB have built-in polarisation offset which means that for the correct offset (twisting of the LNB in the mount) the body of the LNB will be roughly upright. But some don't. So you really should set the offset. Unfortunately the only accurate way is to use something that reads 'signal quality'. You can do it with the receiver's built in meter though. Wait a while after each adjustment to allow the reading to stabilise. Bill |

Consider an octo when you're up there. Also research whether the new Sky Q system needs different LNB feeds from 'traditional' Sky Plus. Yes it does. Sky Q uses a pair of wide band outputs and a digital receiver to get about 12 channels from the two outputs. You can get an octo one with the two Q outputs and 6 old style ones I think. 12 channels? There were only 3 channels when I was at school:-) I'll look into the octo you mentioned. That would actually be quite handy as I have fitted provision for Sky+ in 3 places at their place.

Bundle of 8 cables from an Octo LNB is big and messy IMHO. 4 from a Quad or Quattro LNB is not so bad. Also less connections out in the weather. -- Cheers Dave. |
