I have split the signal from my satellite dish and now nothing works.
Brian Butterworth published on UK Free TV It is not possible to split the signal from a satellite dish.
If you want more than one signal from the dish, you must connect a quad-LNB and feed a signal from it to each dish

yes. each out on the dish will provide independent channels.
you should ask your neighbour first though :)

My house is wired for tv sockets & I have tried to sent signal from sky dish to another room. (Sky input joined to connection to room) but no signal. Signal to room with sky drops when I disconnect but no signal in new room. If I reconnect DTV aerial back I have signal in ne whom. Any ideas ??

Mark: The most likely reason for this is that the socket(s) you are using is fitted with either an internal isolating capacitor or some form of filter, and leads or sockets used for connections to / from a Sky dish have to be of a "direct" connection type without passing through anything, the reason being that a Sky box sends voltages as well as tones to the LNB for band as well as polarity switching purposes, these control signals being blocked by anything in line.
All satellite systems are the same in this respect, whereas Freeview systems are not.

I have an Octo-LNB which has 8 output sockets but some of these O/Ps must be 'low level' signal as some satellite channels do not work and come up saying 'no signal' !!
Is this 'normal' and will these O/Ps be lower signal then a single LNB say?

Colin Swan:
All the outputs should be at the same level and it should make no difference which of the outputs you use as they are identical. They will be at the output level as a single, twin or quad of the same make and design. The variable could well be that the 'F' connectors may not be fitted to the cables correctly on the ones giving the 'no signal' legend. It is vital that all strands of the outer screening and sheathing do not come into any contact with the central core of the cable. Both ends of the affected connections should be checked. If you have a multimeter that has a resistance function you can use that to check that the cables do not have a short circuit once both ends have been disconnected from the LNB and the receiver. If the cable shows a very low resistance then a strand, at least, of the outer is touching the inner and cancelling the signal. It could potentially damage you receiving box power supply too. The ideal measurement in this test is to see an open circuit, often shown as an infinity reading or no reading at all with just the omega symbol.
It is rare to need more than a quad Low Noise Block in any domestic installation. If more receivers are to be fed from a single dish then a powered distribution system designed specifically for use with satellite signals and able to distribute the outputs in pairs (to meet the needs of Freesat PVRs and Sky+ boxes which require two independent inputs). There are many suppliers and manufacturers and these generall provide distribution of Freeview, DAB and VHF FM radio as well. These take inputs from two of the LNB outputs (but I have seen some that use four inputs from the LNB), the terrestrial TV aerial (does not need to be labelled 'digital' as there is no such thing!) and the radio aerials. How they are distributed depends on the make and model, instructions are usually provided.

Hi any pointers as to why a second feed from a quad lnb only works when the tv is powered on on the feed from first port on quad lnb? first cionnection goes to a 'skybox' not sky uk one. second to a Dreambox 600pvr.

It could be that the LNB power is not turned on perhaps. You don't say what make and model equipment is being used. If you supply that then we may be able to check the user manuals.

Hi, I use a variety of machines on the quad lnb - a vu duo takes two feeds, a skybox f5 takes one and tehe dreambox 600pvr takes fourth. vu duo and sky box work fine independently - the dreambox only works if the tv that the skybox f5 serves is powered on, when the tv is on the dm600 works absolutely fine, dm600 running openpli image (enigma 1) cant seem to find a menu or setting for lnb power within it tho.

Hi I live in a council flat with one aerial line
I have sky in front room but recently bought 2 different free view boxes. I.1 Is a basic box which gives me about 10-15 channels through aerial but the other does not seem to work. It's a free view 500 gb re ever a day re order says it needs to connect with TV aerial or ether net or hdmi. Please tell me best way to get it to receive free view without aerial connection.i have it plugged into super hub via ether net but it keeps asking for connection to aerial. Which indoor aerials do you recommend . Please help I am at my wits end and do not know what to do. Thanks u for your patience rhonda

rhonda: If you have any doubts as to whether the Freeview recorder is OK or not, test it out by temporarily connecting it into the outlet socket used by the "basic" box.
Should the box prove to be OK whilst connected into the aforementioned aerial socket, then all that's now required to purchase a "two way" aerial splitter to feed the Freeview signal into each of the two devices referred to, the aerial being connected into the splitters common input.
However, maybe you could clarify on the following. Does your flat have two bedrooms? and if it does, then are any of the two fitted with coax cable type outlet points similar to that seen on the rear of the Freeview boxes?
As far as aerials are concerned, its impossible to give an assessment as to the suitability of any type of aerial unless your location is known, this preferably given in the form of a post code or one from nearby, e.g: a shop / Post Office.
By the way, a Freeview box "has" to be connected into an aerial, the others mentioned such as ethernet can be classed as access to extra facilites via a broadband connection, whereas HDMI refers to the type of connection you are using between the box and your TV, scart being the norm with older equipment.
