aerial question
|
I have just moved house and have discovered that DAB reception is lacking
using the inbuilt aerial on my radio.
Not being keen to start drilling holes and feed cables round the house to
mount a specificly DAB aerial, I am wondering whether the monster (it really
is) TV aerial on the roof will do the job? It points in the right direction
and is already wired all round the house.

I wouldn't think a TV antenna would be pretty poor at picking up DAB
signals. The fact that it is a big TV antenna would not help because all
the extra elements designed to help catch the signals, will be too small
to do the same job at DAB wavelengths. Oh and it would probably also
be the wrong polarisation.
However the fact that it is up on the roof will help quite a bit.
Whether or not that makes up for it being the wrong type of aerial, well
perhaps. Perhaps the simple answer is just try plugging it in and see if
it works.
There may also be another answer. If the problem is not wanting to drill
extra holes and run an extra cable, you could always put up a proper DAB
antenna and use a combiner to send it down the same coax as the TV signal.

As has been said, a TV aerial is not ideal as its elements are not quite the
right length, and may be horizontal rather than vertical. But in practice it
may work quite well!
I have a dedicated DAB aerial (from Maplin) for my main DAB tuner which is
excellent. But I also have a Pure Evoke upstairs which struggled to pick up
decent signals on its telescopic aerial. So I bought an adapter and joined
the Evoke to a TV aerial outlet in the room. The reception is far better
than it was on its rod aerial, and I have never even thought about trying to
link it to my DAB aerial.

The TV antenna will be tuned for band 3 TV from 400-800 Mhz either
with a sweet spot at 600Mhz and falling off either side or with
different bits being tuned for different parts of the band. Either

Presumably you mean Bands IV/V that are used for TV?

way , its performance at 200Mhz will probably be only adequate at best
though it will work.
|
You mean bands 4 and 5. And the expression 'sweet spot' is usually used (in

Yes typo.

So you made a multi-symbol typographical error? That's not a typo, that's a

America) to mean either point on a crystal where it rectifies, or the point
in space where standing waves result in the best signal level.
|
Well in England it mean expression for the point at which something
works best.
|
Like my two examples then. What it doesn't mean is the frequency at which an
aerial has maximum gain. Anyway, next time I'm making love I'll try and
|
Well if it means the point at which something works best then it can
also be applied to the frequency at which an aerial works best. Is
English your first language?

Let's assess this:
Bill is a journalist in his spare time and currently writes for, amonst
others, What Satellite. And Boltar yesterday wrote "its" when he should have
put "it's".
Yep, the only conclusion can be that Boltar's first language isn't English.

bring the expression into the conversation, see how I get on like.

And in England the term is aerial not antenna !!!
|
|
|
Well in Britain its a general expression for the point at which
something works best. Come visit us sometime.
|
I realise you don't like us northerners, but we are still a part of Britain
until devolution.
|
|
As I understand it Scotland and Wales join with England in using the
term aerial rather than antenna.

When I tried this it worked as well as the indoor DAB aerial I've got.
Basically, it'll probably cost you a couple of quid at most to try it, so
you've got little to lose.
