Not true, it depends completely on where you live. Even when we lived in
the northern suburbs of Sydney, we had a masthead amp.

Where we live now, 100% of houses have MHAs coz you don't get reception
otherwise.

Clear line of sight between aerials will have a bigger influence.

Not with digital TV.

Yes, in the sense that you would increase your chances of getting a
usable picture.

splitters.

Digital is very dodgy at best

That's just plain wrong.

If you get it it is picture perfect if you don't you can't

And so is that. You can also get dropouts and pixellation too.

Even if you get it that can change for no ryme nor reason

That's just plain wrong. Only those who don't understand

Recently bought USB TV Tuner: Compro Videomate U620F

Finding that only ABC and SBS is picked up with included antenna. This
is not so bad since the other channels are mostly rubbish, but I have a
few questions:

1. Do the ABC and SBS broadcast stronger signals because they are
government channels and they are required to provide a service?

no. maybe you are closer to their transmitters, or their frequencies are
being received better

2. What influence does the length of the rabbit ears of indoor TV
antennas have on reception?

the longer the better

That’s not right with UHF digital channels.

and he didn't say if he wanted to receive digital or just analogue

He did later, and those usually don’t do analog.

3. What influence does electricity-powered signal amplification have on
reception?

normally it only amplifies what is being received, unless it's a more
sophisticated kind that filters the noise and boosts the signal

Not even possible.

I use this at home with excellent results ..
http://www.hillsantenna.com.au/Products/Product_subcat/Product?cat=8&ProductID=297

Sure, but it doesn’t do that filters the noise stuff.

Is keep out the CB and phone bands and that wont be his problem.

4. Do external house antennas rely on electricity?

no, but you can use a powered mast head amplifier that requires DC
voltage up the antenna cable

5. What would be the best way to improve reception using an indoor
antenna? Antenna size/length? Electricity powered signal amplification?

put it up as high as possible, and you could use something like this..
http://www.jaycar.com.au/productView.asp?ID=LT3133&keywords=indoor+antenna&form=KEYWORD

generally the best solution is to use an external antenna, even a small
one just mounted on the gutter, or in the ceiling unless you have an
iron roof, is better than an internal antenna where the signal has to go
thru walls, etc.

Only rarely in a domestic situation.

Antennas on tops of buildings and blocks of units are another story.

What is the reason they are better than indoor antennas? Height,
electricity, or some other factor?

Having an unobstructed line through the air to the transmitter sites is
the big one - results in a much stronger and much cleaner signal. Plus
you can put up a physically large and efficient antenna that would be
absurd indoors.

It is a near miracle that indoor TV antennas work at all - everything
is against them.

I remember years and years of using indoor antennas.

Yes, but you likely remember that they could be a bit fiddly too.

Is digital TV the reason why they are no longer viable?

Nope, in fact plenty find that their internal antenna isnt very
satisfactory with the old analog TV and does work fine with digital TV.

Same with exernal antennas too.

Where do you plan to use it ?

Small room in accommodation in a capital city without a TV, for a very
brief period so I don't want to spend too much money on it, else I would
purchase a small TV for the purpose. The tuner I bought was only $24.

You'll pay quite a bit more than that for most amplified internal antennas.

Havent checked ebay on that tho, that’s whats in the stores like Dick Smith
etc.

It should work but you may end up paying close to what the cheapest small
TVs cost.

Corse they may not do much better too.

I did do alright by just buying one of those non amplified
antennas at Sams before they went bust and returning it for
a full refund when it didn’t help. The droid just shrugged
and said they get quite a few like that.

I'd personally try one of the cheap indoor antennas from
Chickenfeed etc and if it doesn’t help return it for a full refund.

Or a decent amplified antenna if you don’t mine the higher price.

Its more complicated than that with digital TV where unless you
have enough signal at the TV, you can see no picture at all.

If there is not enough signal at the antenna terminals - it will not help.

Long cable runs and splitters WORSEN the S/N ratio - but only IF you have
them.

IF you live in a rural area, with all channels on UHF, AND are at the limit
of reception distance AND you have a long cable run to the TV or STB - then
using a MHA may be needed.

The issue is the high loss factors in co-ax at UHF frequencies.

20 metres of cable can lose 5 to 6dB of signal.

Yes, but you can see the loss in the cable drop the signal
level down below what the digital TV needs to produce
a picture and a mast head amp can compensate for that
loss in the cable so that the signal is then adequate at the
TV when the signal isnt that great without the mast head amp.

If there is not enough signal at the antenna terminals - it will not
help.

Yes, but if there is too much loss in the cable with a less
than ideal signal at the antenna terminal it can provide
a viable signal level at the TV to get a digital picture.

Long cable runs and splitters WORSEN the S/N ratio - but only IF you
have them.

You don’t need a long run to see significant signal attenuation in the
cable.

IF you live in a rural area, with all channels on UHF, AND are at the
limit of reception distance AND you have a long cable run to the TV or
STB - then using a MHA may be needed.

And you don’t know that his latest situation isnt that.

And you don’t know that his latest situation isnt that.

20 metres of cable can lose 5 to 6dB of signal.

And so you can find that a mast head amp does fix the
problem even when you don’t have a long run or splitters.

Depends on your situation, drive around our town and you'll see MHAs on
97% of antennas. All our channels are on UHF at a distance of about 30Km
from the transmitter with several lumps of terrain between.
