Cabling Convention - 2 Way Philex Digital Signal Booster. Best cables pre made from Aerial through existing distribution neetwork

Posted by on

  • Ian Edmiston Oct 09, 2010

    Very simply. Booster has Female Gold Connectors which may all need to be connected from a an external Digital Aerial. The leads from the outside are already run to wall connections in 3 rooms. There are, therefore, three coaxial leads on the outside of my building two of which are already hard wired connected to become one. I need to run coax cable from the aerial through the signal booster and into the TV. There is one Female Connector on the rear of the TV and two Scart Cable connectors.

    The connectors on the back of the 2 X Signal Booster are identified thus left to right:

    UHF FMDAB 1 2

    I will be connecting to the aerial on Mondusing a hired Platform for that day. I would really like a simplified connection diagram advising what connections should be made and to where on the TV, The TV is a DMTECH Model LM1708.

    Hello, I agree that this question is simple, but it's also a bit complex. From my understanding, you have an aerial/antenna that you want to connect to 3 room or 3 TVs.

    Is the above what you mean? Please confirm.

    I'm sorry for all these question, but I really need to be sure, so that I can proffer an accurate solution.

    Take care.

No snow just says to scan chanels . I have over and over

The TV signal is no good if it cannot find any channels. You will have to check the signal cable and its connections right back to the aerial. You may even need a better aerial or a signal booster. Digital TV needs the very best of all these or the picture just goes to porridge.

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 before noticing the red "fault" light, my picture had gone to pot.

How to use 2 way tv signal booster

On the booster there should be one input plug (probably labelled antenna, or AE) and two output plugs (probably labelled TV1 and TV2). The cable from your aerial should go into the input plug, then your tv should plug into the tv plug.
It's best to have a short a cable as possible from the aerial to the booster. Often the booster is fitted in the attic, with the TV cables running to the appropriate rooms. This prevents the booster from 'boosting' any signal noise.

I have just moved house to Reading and previously was able to view freeview tv using my old indoor aerial in my 2nd floor flat in london. This indoor aerial didn't pick up any signals, not even analogue,...

You will need to have an outdoor aerial installed, the signal area you're now living in will not be a strong enough reception for an indoor aerial no matter how good or expensive. You could try the indoor aerial in different positions around the room especially by a window to try & pick up some other channels but the long term this will cause some of the programmes to break up or freeze. An aerial on the roof or in the attic will be your best solution to pick up all the digital channels on freeview.

I keep loosing digital signal with both my digital tv's, I have a digital aerial fitted 18 months ago. what is the problem?

This can be due to a few problems.Firstly make sure your aerial is pointing in the right direction as beam aerials attenuate(disregard) signals which are not pointing directly at the aerial.
make sure you are using good quality 75ohm cable i.e rg6 and connections are good and not shorting out.
The length of run of the cable will also affect the signal as will any splitters or joins in the cable.
If you know the signal is good in your area then it will be down to the aerial,cable terminations ,aerial position or a combination of these.
If the signal is poor you can either...Buy a high db gain arial which will amplify the signal and or a masthead preamp which will again boost the signal.
please note that if your aerial is not pointing in the correct direction then any boosting of a bad signal i.e ghosting...will only make it worse.
try starting from aerial direction then connections then a high gain aerial and or booster.

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.

Hi and welcome to FixYa,

To get a good signal on all TV units, the source must be good and strong. The source could be an aerial antenna or connection to your local cable provider. The message "No Signal" indicates that the TV cold not receive a decent TV signal. With this in mind, possible solution wouold then be to increase/improve the incoming TV signal:
  • if you are using an aerial, 'height is might' to overcome any line-of-sight obstruction. Additionally, there are antennas with higher gain, meaning they could receive better than other antennas. Another option is installing a pre-amp or commonly called booster;
  • if you are hooked to a cable provider then it may be to your advantage to bring this concern to their attention. They could try transferring you tap off point to a better distribution box, replace your coaxial cable with low loss or even in some cases, install an inline booster;
  • possible RFI (radio frequency interference) which could come from wireless phones, garage door openers, WiFi, electronic dimmers, electronic ballasts of high density lamps and others. If any are present or within the immediate vicinity, pls try to relocate or reposition.
Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

Tv no channels at all

Dear Mrice001

Righteo, the first ting you should avoid doing in this situation, is what millions of people would do when they eithe have little or no TV signal, what they do is to rush out and buy a signal booster. Now this is very wrong, as the signal is not improved as such. Any distortion or "noise" is also amplified with a booster, so this is a futile effort. What you are probably best off doing, if you have a digital aerial is (if you are going to add a booster) is to attach the thing as close to the aerial antenna as possible (up to about 500mm from the aerial base where the coax cable joins the mast).

Now if your TV is still not working, then i reckon that you should investigate the box that both your TV sets are connected to. This includes all of the cabling too. It might be well worth checking that both of your TV sets have SCART connections to the cable box, and that there are enough channels to both TVs from the box, (ideally there should be two or three SCART connections on the box) if not, then you can use a SCART adapter, but you may loose picture quality on one of the TV's.

Once you have set all the wiring and cabling in plce, it is time to pair the TV to the signal that you want to recieve. Now your user manual will tell you on how to scan and save the channels to your TV set, or for freeview, sky, NTL and cable, then all you need to do is ensure that your TV is tuned into the box (in your case it will be the cable box). Now setting this to the AV1 channel will be best (just as long as you have good SCART) or you can run your TV's tuning setting through the coaxial 75ohm cable in order to pickup the signal that way. SCART is prefffered though as it gives better picture ratio, quality and is faster to tune.

Now, should all of this not work, then i recommend getting hold of your manufacturers/ vendored model of i you hit up

and type in your device builder ollowed by the words "manual, user guide or technical specifications" then you should return a whole bunch of eye candyishresults or you to read and understand.

Should you still have a problem, then you can always get hold of me here and I will be more than glad to help.

In the meantime, i hope that this is the fixya for you.

All regards, and best o luck on this one

yours sincerely
