Most households probably have a TV in the living room, plus one in each of the kids' bedrooms and possibly several other TVs as well. Take a look at the rooftops. You'll almost never see a house with two TV aerials on it. That's because all of those TVs are using a single aerial.

Splitting the signal between two (or more) TV sets does lead to a loss of signal strength but it's not as great as you might think. (You don't simply get a half-strength signal down each cable. The actual signal strength along each cable is only slightly less than down a single cable. It's all to do with logarithms!).

A good quality aerial, with good quality cabling, can usually feed two or three TVs without the need for additional amplification.

It's not about logarithms .. that's a mathematicians answer. It's about Gain ... DbA ... and signal quality versus noise.
It's especially important with digital signals.
You should use a always distribution amplifier or active splitter when splitting signals, otherwise you will likely not receive all the Digital MUX's (channel packets)
LOL!!

Yes most decent TV aerials can quite comfortably run 2 TV's off them perfectly well with a simple splitter.

(remind me again, what sort of scale are gain, and DbA measured in?)
Not being technical I'll just say yes.......
That's boll$cks
Passive splitters are no good now.
Every TV antenna is "decent".
High gain, directional, and Yagi build type are most important now.
Stick to I.T.
Only exclusion is .. if you live on top of a transmitter.
You men are very sexy when you argue about technical stuff.

I'd back Chukky in a Harry Hill -type fight anyday!

He's very clever
A helmet would
Me too..............he is 6'6"..........
especially one with a FS1E in the shed.
6' 6" That's just the neck
Who's chukky (not the doll presumably?)
The thing is ...
You amateurs who just do a search on Google for answers on issues like this that you don't know a lot about, do not realise that for most people, it is really important to have a good and properly aligned antenna with decent amplification for digital terrestrial signals. A lot of people live at the moment in what is called a "fringe" area which requires a proper setup. Old 50 ohm downlead, passive splitters, joined-up-with-tape downlead all produce degradation or noise in the signal. You will have problems like have been asked about here before.
(stifles yawn..) Yeah right.....
Purdie. I've seen you on here before and you do appear to be quite dim. I was referring earlier to Chuckfickens. And who mentioned a doll?
That answer was for those who don't spend their time stuck in "Easy Rider" magazine (or FS1E Riders Monthly)
Well I've seen you on here before too so I'm not going to stoop so low to defend myself to you

Goodnight AlBags xx CF, Chris et al
