Yes the cable length is important, however in most cases if you are hooking up coaxial cable that is 50 feet or less it's not going to affect the signal that much. If' its a lot more than 50 feet in length and the signal isn't strong enough to provide good video quality they do sell inline amplifiers. I hope this helps but somtimes it's a trial and error type of thing where you hook it up and it either works or it doesn't and you have no choice but to install an inline signal amplifier.

No tv channels found on autotune . Aerial is in Loft.


To get a 6 way or 4 way signal, it has to be amplified. Does your splitter have a power connection to it. If you just have one lead going into a block and 6 outlets, that is for a high gain signal to go in that is already amplified. You can test by disconnecting all the leads but one. Use the closest set to the loft and use that one to get the sharpest signal by turning the aerial left and right. It has to be in the right direction and if it is off by just two degrees, you will not get a picture. Also aerials and better situated outdoors for the best signal.

I have a Panasonic tv model TH 42PZ80B; a Panasinic Blu-Ray dvd model DMP-BD50; a sky box (not as yet HD) and a Sony video SLV-SE 830G. I have a Satellite dish and a normal TV aerial. In the loft I have a...


You need to try and isolate the piece of equipment which is causing the problem.

You've already tried the aerial lead direct to the TV and this is OK.

Disconnect all scart leads and try the RF on its own.

Try the Aerial lead to video, then video to TV.

Try aerial direct to Sky box, then to TV.

Try just connecting the RF out from the Sky box to the TV (no aerial input), can you tune into a good channel 68 picture from the Sky box.

Then Try the VCR to the Sky box (no aerial input), see if you can tune into the VCR and Sky channel.
Hope that helps.......

Can you please change the input device to some other you know, works? If you do not notice any problem there, look for the aerial cable going close to any power line or has interference from some other transmissions of any kind nearby.

My Tristar TV signal booster has a red light illuminated, I think is says 'short' above it. Is the booster working? I have fault on my TV it maybe this. The booster has been working fine up till...


I too have a red "short" light on my Tristar booster. However- I've illiminated the Tristar as I unplugged it and connected my tv directly to the 13amp mains and b) connected the aerial directly to the aerial wall socket which is separately boosted from a distribution amplifier box in the loft. Picture was U/S so the "short" is probably in my cabling in the loft (I've been moving the aerial about lately).Hence I suggest initially to unplug the Tristar and check the fault is not back further up the line ie the cable and booster at top of house. Hope that all makes sense.ps before noticing the red "fault" light, my picture had gone to pot.

My neighbourgh can get freeview tv just using his old ariel, i on the other hand can not. have i done something wrong with the tv set up. thanks


Probably not. Freeview signals are hundreds of times weaker than the old analogue signals, so will show up every single problem on a badly maintained, badly installed old external tv aerial.

In most areas, a tv set-top aerial is a waste of time and even a loft aerial may have problems. Any aerial system which is not direct from the external aerial to the tv can also suffer problems, as each Y-splitter and joint wastes an awful lot of signal.

Your fix is to get a proper modern aerial system fitted. If it's well designed and installed with the proper parts and cabling (does not necessarily mean most expensive) then it should last for another 30 or so years and ideally won't need signal amplifiers.

Note that although your neighbour gets reception, he probably suffers regular picture break-up, freezing and /or pixellation especially in poor weather unless the aerial was in top condition beforehand and was relatively modern.

If you want to watch Freeview, then you need an aerial, preferably a proper external (or loft mounted) one. Freeview signals are far weaker than traditional tv signals and so trying to receive them without an aerial or via a tv set-top aerial is usually doomed to failure. If you must use a set-top aerial then connect it directly to the tv (not via a video or any other device) and avoid using "amplified" or "booster" aerials unless you have no other choice.

I'm unfamiliar with Vistron, but usually channels are added by going into the menu and looking for "installation" or "set up". But if you have no aerial then you aren't going to get very far.

Since digital switchover yesturday loss of digital channels


It may well be your aerial despite the success with your DVD recorder.

Digital signals are very much weaker than analogue ones, and when multiple devices share a single aerial you can get this kind of problem. You also lose about 60% of the signal at each point in your aerial cable where there are signal splitters.

There are a number of possible solutions:-

First, look at every bit of coaxial cable you have between the aerial and each appliance. Check especially at the aerial end for corrosion or poor shielding/installation and especially for evidence of rain water penetration. If the aerial is on the roof then it will cost almost as much to get the aerial inspected as it will to have it replaced, so skip to the next option. But otherwise, check along every bit of the cable for any cuts or splits in the insulation and properly remake every junction or joint if there are any doubts about them. If the cable is in poor condition then consider option three instead.

The second is to try to see if you get a better digital signal from another transmitter, this will involve trying different aerial positions so is impractical if your aerial is roof mounted but is worth trying if it's in the loft instead. It doesn't always follow that your best digital signal will be from the transmitter which you used for analogue transmissions.

Thirdly, if you're still using the same aerial as you have done for years then it's worth upgrading to one optimised for digital reception. When doing this it's foolish not to replace the cabling as well as you need it to be as good as possible. With analogue, many installers got away with using cheaper cable intended only for very short cable runs from the wall socket to the tv.

The fourth option is the budget option but can work as well as the third option: fit an additional analogue style aerials and run a separate cable down to each appliance. If these are fitted in the loft and you have the space, then there's no aesthetic or planning concerns. Normally the extra cables can run partway down through the house alongside existing cables, but for best signal quality keep them separate and ensure that the cable runs as as short as possible.

One further thing which you may want to try before all else: connect your digital box directly to the aerial cable which currently feeds your dvd recorder. Leave all other tv devices disconnected from the aerial. If the box retunes correctly then it's definitely a supply of signal issue as outlined above and if not then you should add the exact make and model of your digibox as a comment to this answer as there are a large number of earlier digibox models which cannot retune correctly due to evolving standards.

Radio cable length from rear aerial


no - the factory cable is a one piece cable to the radio- what you can do is to cut off the end that went to the original antenna replace it with a female antenna end and just plug the new antenna into it (easiest way)
