Was wondering if there`s such a device as a `splitter` that can make one aerial lead divide into two, enabling the use of a long aerial extension lead to another set? And if so, is it likely to adversely affect the quality of the picture on the TV screens?

There are hundreds of them, like this Aerial splitter.
if you have a good signal you won't see much deterioration. To be sure you can buy a signal booster with two or three outlets, like these.....Signal Boosters.
You can get them from your local supermarket if you don't want to buy on line....

an old fashioned Y splitter will split the signal to 33 / 33 % to two feeds rather than 50 / 50 as you would imagine

a Y splitter should be held in your hand like a wee man. The head is input and the two legs are the outputs

a powered one is preferable as already expressed , however I would say they are really called distrubution amps rather than signal boosters , but its horses for courses. Get one like this one with a bypass built in for future proofing or sending sky round the house and controlling it from another room. It aint dear

Many thanks,guys; I thought there must be something todo the job, but haven`t seen one in any of the places I`ve looked so far. I note that one purchaser thought the Y type splitter was useless as it lost the picture on one tV completely and the other TV`s picture was poor. I suppose the signal booster device would sort that problem out.

I receive digital channels from 2 main transmitters (Wales & England) and therefore have 2 loft aerials each aimed at a transmitter. When digital TV came along, I no longer needed to use a switch to go from one transmitter to the other. I purchased a 3 way splitter/combiner from Asda for about 3. (You will also need the plugs to fit into the sockets - one of which is different to the others male/female).

I get perfect pictures including the HD channels.

Bad advice, they sell the plastic unscreened cheap rubbish ones.

A proper metal screened design will be way better.

I have a loft aerial which is shared with a TV, PVR plus Laptop & PC with tuners.
I've tried various splitter/boosters and they've all been rubbish to the extent of the signal actually being worse with them connected.
However I found a SLX at Amazon and it is really excellent.

In your opinion.....If you had one and it didn't work I hope you took it back, If you didn't have one........

Before getting a distribution amp definitely try a simple Y splitter first. It may well be enough and is much cheaper and simpler (no power needed), if it doesn't work well then you haven't lost much by trying.

grahamlthompson is right.

Splitting close to the TV (and hence far way from the aerial) is never a good idea, but folk do it because it's convenient. Chucking in an unscreened plastic splitter isn't going to help; and for the cost difference of literally pennies it's a false economy too. The cost of a screened splitter isn't going to break the bank LINK . So there's really no need to buy junk, is there?

How so, wouldn't it be around 3.5db loss from each output?

it will only be 3.5dB from a good quality screened splitter, usually in a sealed metal container with screw on f connectors..
Cheap plastic y splitters are very inefficient.

Nice to see he has a fanboy!!
The link you gave is not talking about the same product! Neither did GT's as it happens....Still nice to see you were all paying attention...

Screening in no affects efficiency, cheap plastic Y splitters are generally just as good as more expensive metal ones, and many plastic ones are actually screened under the plastic anyway.

A more expensive 'obviously' screened one 'may' be better, in the one in a few thousand cases where there's some local interference that the screening 'may' help reduce.

But in the VAST majority of cases they will perform equally as well as each other.

Well now, where to begin...
grahamlthompson's information was sound. Agreeing with that doesn't make one a fan boy, just a sensible person. I take it you disagree?

The link I gave was in response to a specific post (#10) and provided some valid justification based on price and quality. That's called a rational argument where I come from. But I guess you have a different view?

Finally, "as it happens" my link referred to a product on the same page from your very first link. I think the phase "hoisted with his own petard" applies.
I know what you're thinking now. You're itching to type that you were talking about the amplified splitters - hence your comment "Neither did GT's as it happens" - but that overlooks your dismissal of glt's point and the beginning of another facet of the discussion. Do try to keep up

Try putting one anywhere near a hdmi lead. I took one apart once it had a few components roughly soldered together (no circuit board to mount them on) and a tiny square of aluminium was so the so called screening. Complete junk.

So you've found ONE junk Y splitter

Most of the Y splitters I've seen use full metal casings with two plastic halves clipped over them.

Perhaps you should buy better HDMI leads if they are radiating interference

Perhaps that will teach you to read the whole thread. GT's point was dismissed because, like yours, it was off piste.
If you two wish to waffle on about the merits of splitters then fine. I don't agree or disagree with the points you make on them. However, that is not what I was referring to as well you know, but, I suppose you are locked into this petty argument for the duration now.
(Catching up yet?)

Without dismantling the thing how would you know if it's junk or not. The difference in price for a metal one is so small that it's seems just stupid to not buy the better quality item.

The metal one you get a spec, what do you get with a plastic one - zilch.

eg

A range of high performance splitters specifically, for use with digital satellite and digital terrestrial UHF TV distribution systems, with minimal insertion loss, high return loss and isolation.
Operating frequency 5-1000MHz
75Ω F type connectors
Ground terminals
Zinc die cast housing
Die-cast fully screened alloy housing to EN50083-2
Earth bond provision
F' type RF connectors
Fixing screws included

I believe the OP was referring to the signal boosters that call100 linked too in post #2 - call100 was
informing the OP that they could get one from their local supermarket, Tesco/Asda.

Agree it was a rude remark by call100 - tut-tut

Apologies if I have spoken out of turn.

The one star completely useless review kind of says it all.

Comparing the two items linked to the metal screened version is actually cheaper than the plastic non screened version from B&Q.
