tuning in new tv



We've just bought our eldest a new tv.
I have an aerial booster from the aerial socket downstairs to a cable upstairs, and this has been fine for old tv's in the past.

However, this tv is a digital thing and when you ask it to tune in, it searches and vaguely finds channels, but never 'locks on' to any.


Should this tv find the 4 terrestrial (analogue) channels?

does it need a didgital aerial?

How can i tell if i have a digital aerial?

If i use my main telly, this picks up on didgital:

BBC News
BBC red button

and analogue

You can get a difference in reception because the TV tuners are of lesser or greater sensitivity. Add to this that the TV signal to your daughters room runs via a tap off from a splitter/booster. That device will add some noise to the signal, as will the additional cable. This means more noise and less signal by the time it reaches your daughter's bedroom.

Do you need a digital compatible aerial.... the answer is yes/no/maybe

If you can get a decent amount of digital channels on the main TV then you probably don't. If, after retuning, you still can't get that many on the main TV then maybe it's time to get updated.

Ignoring the digital switchover for a second, aerials themselves don't last forever. That goes the same for the cable too. They both corrode because of weather and UV exposure.

Cable quality has also improved leaps and bounds. The old and hardly-shielded brown TV coax is only sold by builders merchants and DIY stores now - which is why a builder should never be trusted to put up an aerial or run TV cables in a house. Those of us who know what we are doing use something significantly better and we also know that bending it too sharply blocks certain frequencies.

Test your daughter's TV downstairs connected to the main aerial point.

If you'd like some decent quality extension cable then drop me a line. :)
