CABLE AMPLIFIER IN LINE !!! IS THERE ONE and CABLE FILTER

[WOODWARD395]

was going to fit cable inline amp if there is such a thing got slight pixelating on all channels checking all cables today but was just wondering if there was such a thing as I know there are mains operated amps.

another point there is a small cable filter in line e.g. 4dB 6dB etc. do they reduce the signal what do they actually do.

Buy Ebay crap dont expect anything good out of it.

Ok got my answer the best way to increase your cable signal is to have the engineer do it for you or you could buy an amplifier of EBay !!!!!!!!!!! as for the filters they reduce noise on your line and they do reduce signal strength.

But Eureka solved my issues with the signal I suppose if you buy crap of eBay you get crap bought my cable splitters of there
all in the bin now as discovered they are all faulty reducing signal strength considerably I have now put a good quality one in line and great signal now no pixelating. Live and Learn

Glad you got it sorted....but what splitter did you use? and where did you buy it from? this will help others with the same problem.

Bought them some time ago for another sat Job but never used them until this week so cant remember just went for the cheapest at the time like an idiot replaced it with an old NTL four way splitter picture is great now, apart from my ECM'S go up to 6.013 and I get a picture freeze about every 15 mins intermittently I may have other issue's I think.

Back in the day there was the Konig yellow brick that helps to boost the cable.

I have used that in the days of starview sorry for swearing was more trouble than it was worth could never get it to boost the signal sufficiently mind you bought that of ebay say no more.


probably Chinese copy.

if using a cable signal booster it needs to be a good one like the Konig as previously mentioned, try and get a genuine one and not a joke one. Like this one here >>> Konig 30dB Digitial TV Signal Amplifier with Active: Amazon.co.uk: Electronics
(thats what I used by the way when I had cable, used it for both the modem and the TV box, worked perfect, infact I will still have mines laying in the cupboard along with my Genuine boxed mint condition dreambox 500c too).

You can then adjust the signal strength and return path etc, from what I remember this is especially important if using to boost signal strength to a cable modem as not all boosters work with a cable modem.

But, if your only needing it for the TV cable box then simply fit it on the line after the splitter that runs the cable to the TV box, simple as that, and dont turn the signal up too much as that just fercks up the signal going to the box and will make it worse, you need to turn the signal strength a tiny little bit at a time and watch your signal strengths on the weakest channels, get it so that they are just perfect and then stop, you have to comprimise as too much strength as I said makes lots of channels worse.

20140702_221109.jpgi used the red and silver splitter in the pic and had problems with pixelating, i swapped it for the 2nd pic.. the green one and its purrrrrfect now.. nicked it from a nieghbours brown box outside his house as he didnt need it.20140702_221022.jpg

Thats them mate, thats the best splitters that Virgin use you have there, called " QAMTEX", the green and white one should only be used as the cable comes into the house from the street ( I dont know why, but my experience with them I could only use it that way) and then the red and white ones wherever else you need to use them, it is never a good Idea to have anymore than maybe 1 or 2 splitters though not including the green and white one, Unless you have a really really strong signal coming in the house to start with, thats different. (The more splitters you have equals more interfierence in the cables and therefore more modem disconnects and picture freeze ups etc and if you then also have a booster it will boost that interfierence too which makes things 100 times worse unless booster is fitted in correct place on the line).

Am I going colour blind or are the pictures the wrong way round striped every thing back today had a 6db and 4db filter outside in line coming into the house on the line just before router I have a 6db filter so have put 6db filter on the splitter going to router and removed the filters from outside.

I am presuming my signal is strong enough because of all the filters on my BB line I have a perfect picture all the time apart from a complete freeze for a second approx. between every 6 to 12 mins.

I originally had serious glitching and found out it was the cheap splitter I bough from eBay that was the culprit just as a thought whilst I am writing could it still be the splitter I will change it tomorrow again after a visit to the sat shop to purchase an even better one but will try another test later.


I initially connected the cable directly to the box and scanned for my channels. I will remove the splitter tomorrow and try direct connection as the Mrs wont let me disconnect her big brother tonight to try it.

should have done that in the first place after I had scanned.

Those filters will be negative gain. Normally if you have them its because you have a strong signal. I'm the other way round my signal is pants.

So am I right in removing them to get a stronger signal. what would be the effect if the signal was too strong would I not get a ghosting effect or is that just with ****ogue signals.

[andy91]

All I know on some images it will tell you what db signal you have and if its around 40db you're on the right track. Ive a few in the high 20s and it glitches but a high a db is also bad hence them adding the attenuators.
Easier for them to bring the signal down and adding splitters you also lose db.
Try just main feed and no splitters if you can.
Other thing could be your box ive a few DM800C and on one box its terrible.

lets try and find out first just how strong the signal is from the main feed without splitters apart from just having your tv box and modem connected which usually means just the one single QAMTEX splitter that Virgin installed that should have one feed to tv box and one to the modem unless you paid for multi room, that's different and you would need to state exactly what came fitted when you had it all fitted with Virgin (forget any self made connections you have for the present time), then we can look at the signal strength on the tv box and the modem and check that it isn't too strong, there are certain pages you look at on tv screen menu for box that will tell you the info (people will be able to advise you on that, I cant remember as I don't have cable tv/modem anymore), we can also pull up a screen from your modem same way that will give accurate details of the signal strength at that point too, I think its usually 192.168.0.1 or something like that, I cant remember as I said, but someone else will defo be able to tell you.

As for these issues, I was plagued with similar issues when I did have cable tv/modem years ago and nothing has changed, I know that, and I sure as heck know the best ways I found to solve the problems too, , its not a big deal to be honest, just a bit of time and testing etc, that's all.

yeh pics went on wrong way round fella but i did well getting them to upload . i didn't know how to swap them round and it placed them where every it pleased. I was trying to get them both on the end of the typin.
