Powerpoint iin the loft?
I just bought a Freecom USB DDTV stick so I can watch (and record)
DDTV on my PC, however as my reception/(signal strength) is not too good I had to buy a signal booster as well as I have to split the signal, it is one of those ones you plug in to the mains so I used it in the 'living room' where both the TV and PC are. It seems to work find, however I an not too sure if the picture(s) are a little more 'fuzzy', perhaps due to noise from the amplifier? Anyway I have decent enough pictures on both 'sets'. I did think I would be better off with the booster in the loft closer to the original signal, it could power the connection in the kitchen from their too, and I could use a passive splitter downstairs?, however I have no powerpoint in the loft. Obviously there are wires for lighting in the loft, but will they only work when the light is switched on? I could simply run an extension cable up there, but that wold lok a bit messy. Incidently the Freecom USB stick seemed more sensitive than my Sagem Freeview box. When I tried with a passive splitter I got a great picture on the PC, but bugger all on the TV, and this is despite the cable to the Freecom stick being of (significantly) lower quality (poorer shielding). However Sagem's user interface and EPG seemed much better. |

This has been covered in depth before so a Google will help you. Briefly, the nearer to the aerial you amplify the signal the better, although always keep amplifiers a good metre or so from the aerial. To power the amplifier in the loft you can take a feed from the lighting circuit, if you take it from the supply between each light rather than a switch wire you won't have to worry about it only working when the light is on. Open up a convenient ceiling rose upstairs and you will be able to trace the feed cables, and tap in there. Sleeve your earth cables! If the amplifier has a flying power lead, snip off the plug and connect it to the lighting circuit via a 3amp fused connection unit with double pole switching http://www.screwfix.com/app/sfd/cat/...27148&ts=67719 If the amplifier is built into a 13 amp plug (a wall wart) use the http://www.screwfix.com/app/sfd/cat/...27148&ts=67719 with a 3amp fuse to feed a standard 13 amp socket and plug it in there. This prevents any future occupiers using your socket to plug in a 3kw fan heater which would blow the fuse in the consumer unit and leave them in the loft in darkness! (Using a 3 amp fuse in the loft provides some discrimination which should hopefully fail before the CU fuse does.) |

For the best signal (technically, signal-to-noise ratio) you need to boost the signal as near as you can get to the aerial; in your case, that's in the loft. My booster is in the loft, and I power it from downstairs with an extension cable in the same wall-channel as the pipes from the central heating boiler. Using a splitter downstairs is OK. |

Yea I kind of know that, the picture I probably the same but I am just 'looking for' interference. I was thinking maybe small bit of interference might cause 'fuzziness', anyway it says 98% signal quality, which is the highest it has ever registered, it has never said 100%. So I think 98% might mean 100%, either that or it's because the aerial is in th loft. Your fuzziness might be caused by: 1. TV companies insisting on still transmitting interlaced signals that only flickery pre 1990s TVs can display properly. I think they reduce bit rates too, to squeeae in more channels. 2. Your PC screen being of significantly higher quality than an old CRT TV, so the imperfections in the picture are more apparent. 3. Some sort of software issue, such as turning on some sort of filter that you don't need. Christian. |

So I think 98% might mean 100%, either that or it's because the aerial is in th loft. Actually I have fixed the 'fuzziness' by connecting to the TV via scart, I was using a RF connection and something was interfering with it. I heard a police car do past and I noticed it produced and interference pattern, which gave me a clue to the problem. Your fuzziness might be caused by: 1.

No. Part P does not apply to extensions off existing circuits apart from kitchens and bathrooms. Part P does not require the work to be done by either a competent or a qualified person. Owain Oh, dear! Got it all wrong again. |

I guess I need to find the wire from the switch, fortunately I will be using a bathroom light which has a switch in the ceiling so that should give me a good clue. There will be an alway live wire there. So......... I will be able to get a live and neutral wire at least, not sure if there is any earth (only remember seing two wires when I loooked in the loft. So I can either forget the earth all togeather or run a wire to a bit too exposed pipe work. I guess I can test if it is earthed by touching it with the live wire :O) That way I will have four power points in the loft and still have a plug on my amp, which incidently is basically a 'plug' ie it has no cable. |

I really don't think you should be messing with the lighting circuits. Buy a few metres of 5amp three core flex and wire one end to a "cable end" or "floating" 13 amp socket (the kind with a cable grip - usually rubber). Poke a small hole in the ceiling at a convenient place and push the wire through and fit a 13 amp plug with a 3 amp fuse, then just plug it into a socket. There's no guarantee that the booster will work any better up there. If you are feeding two aerial inputs a booster which has two outputs might be better rather than using a passive splitter. I assume your Freecom USB DDTV stick doesn't have "passthrough" (i.e. an aerial output as well as an input). It's always better to "daisy chain" appliances together if possible, like the way you wire a VCR and a TV up to the aerial. -- Max Demian |

Thanks. The problem with asking such questions is that the respondant usually assumes you are familiar with the terms and jargon of the trade. Indeed I have a DIY manual which falls into that trap!! The tell you lots of things you don't what to know and omit the bits you do!! "feed from the lighting circuit, if you take it from the supply between each light" I assume a 'feed' is some sort of wire, rather than a ready made meal. Anyway OK if I open up the ceiling flower I will see lots of wires I did last time I tried it :O) So how will that help? You see I am not familliar with household wiring, If I was I propably wouldn't be asking would I!! Anyway as far as I can see there only need to be two wires, a live one (when switched on), and a return wire. Anyway I will assume there will be a whole bumch of wires there as that is what you imply. "Sleeve your earth cables"???? Sleeve? I don't think I have an earth cable that I am aware of? What can all that mean? "flying power lead"... hmmm....is that something to with aviation, will I need to take flying lessons? Sorry, my mistake, I had assumed this was a tech newsgroup. Call an electrician. OK I will stop this nonsense, What I am perhaps thinking of doing is taking a cheapo short (four-way) extention cable (costs about £1-£2) and taking off the plug to expose the live earth and neutral wires. Then I will try to connect them to the existing wires somehow from the ceiling rose. Anyway acording to this diagram I wont find the 'always live' wire at the ceils rose. So how do I find it? I guess I need to find the wire from the switch, fortunately I will be using a bathroom light which has a switch in the ceiling so that should give me a good clue. There will be an alway live wire there. So......... I will be able to get a live and neutral wire at least, not sure if there is any earth (only remember seing two wires when I loooked in the loft. So I can either forget the earth all togeather or run a wire to a bit too exposed pipe work. I guess I can test if it is earthed by touching it with the live wire :O) That way I will have four power points in the loft and still have a plug on my amp, which incidently is basically a 'plug' ie it has no cable. You won't usually find a neutral at a light switch. If your lighting circuit is not earthed your wiring is old and probably needs re-wiring. Do not use it to feed any sockets - it won't be safe without an earth. What you have suggested is dangerous and does not comply with current (or past) Regs. |

Given this pointer to the level of Mr Smith's electrical expertise, I really think that subsequent posters who encourage him to make a connection to a lighting circuit are offering dangerous advice. Can't help thinking that encouraging him up a ladder might be unwise enough. Couldn't agree more - and most eloquently put, if I may be so bold. What's more, new laws about such things prohibit dabbling, I believe, except by qualified personnel (competent isn't enough these days, so even a knowledgeable mate is a dubious solution methinks?). No. Part P does not apply to extensions off existing circuits apart from kitchens and bathrooms. Part P does not require the work to be done by either a competent or a qualified person. Owain why would you want to run presentations in the loft, surly the office is a better venue? lol |
