Re: Poor signal and missing channels

Yes that is correct. Both box’s signal strength and quality are the same.

 

The 2 TVs in the house that used to have sky used the dish for all channels. The other 6 TVs in the house always used the roof aerial to run freeview as it does today without any issues.

I have no idea about a power converter. Not technically minded sorry.

 

 


I have no idea about a power converter. Not technically minded sorry. The distribution amp will require a source of power just like any other electrical appliance, the question then is does it work straight of the mains or is it connected to a device similar to a mobile phone charger?

You said earlier that when you bypassed the distribution system that you only got 13 channels, but in your last post you said the other 6 TV's were working correctly, are you absolutely certain that you tuned the boxes in to the strongest transmitter for your area?

Re: Poor signal and missing channels

The distributor runs off mains power direct from box. No transformer.

Yes that is correct the freeview built in to the 6 TVs receive every channel available but I have just noticed that a few of them are actually pixelating.

Can I check what transmitter the boxes are tuned to?

Re: Poor signal and missing channels

Easy way is to look on the TV guide for the local news programs on BBC1 and ITV.

Alternatively you could re-tune, at the end of the tuning process will be asked to select your region etc.

If the other TVs' are also pixelating then I would say you need a new aerial and/or distribution amp

Re: Poor signal and missing channels

I have just tried a re-tune and it doesn’t ask to select the ruin at the end of the process.

If I try the low cost option first i.e a new distribution amp, is there a particular model you would recommend? Needs to be 8 way with fm and uhf in.

Re: Poor signal and missing channels

With you not being technical, it's probably best to start with what you have. By that I mean keep the same kind of terminations (connections) that you already have, this should make the job easier.

My preferred brand would be Labgear, but they tend to terminate in 'F'  connectors (the same type of connector your dish uses to connect to your Sky box). Others use ordinary UHF sockets (such as the aerial input on the back of your TV).

To keep the job as simple as you can I would recommend checking if the model you currently have is still available.

How old is your aerial and how exposed are you where you are? Sometimes its just a case of water getting into the terminal block on the aerial and/or wind causing movement in the co-ax where it terminates on the aerial, the middle core of the cable then snaps and simply needs to be re-made

Did you check that your aerial is pointing in the same direction as you neighbours?

Re: Poor signal and missing channels

I agree but I cannot find a Labgear 8 way distribution amp with rf (uhf) connections. I have however found one by a manufacturer called SLX. Are you familiar with them?

There is a Labgear LDA2081LR which is 8 way but has the f type connections. But I have noticed you can buy f type to rf connection adaptors. Would these do the job?

The aerial is about 8 to 10 years old. This was upgraded when tv turned to digital. My current distributor is an 8 way by Fringe Electronics, this was upgraded the same time as the aerial. We have actually bypassed this and I got a weaker signal. This is why I’m in 2 minds whether or not to replace.

The aerial is pointing in the same direction as our neighbours.

Re: Poor signal and missing channels

You won't find a Labgear one that use UHF plugs. If I wwas doing the job, I would re-terminate the aerial cable in F connectors rather than mess about with adapters. 

Yes, I am familiar with SLX.

8 -10 years is nothing for a TV aerial these days, mine is about the same age and I have no complaints.

I'm starting to think you've got water ingress inside the co-ax cable outside or a bad connection where it connects to the aerial

Re: Poor signal and missing channels

I’ve have found the problem. I purchased pre assembled coaxial rf cables from eBay for both bt tv boxes. I thought I would just try the rf cables from one of the other rooms just to eliminate the cables and I can now receive most of the channels and near on perfect signal.

I wouldn’t of guessed it was the new cables.

Re: Poor signal and missing channels

I suggested labgear as a brand, I did not suggest any particular model, the OP asked me if that model would do the job.
