Do you get a good analog reception?

If you are getting a good analog reception then you will get a good digital reception
If analog is bad, then No, you will need another antenna

What kind of antenna is that? Is it one of those small indoor type antennas? They are extremely bad and i wouldn't even get one for $5.

If it is an outdoor antenna and you still get images on your TV but which are very noisy to the point where watching it for more then a few minutes would start giving you eye aches then a digital set-top box is still able to decode the signal and display a perfect picture. Thats what its like at my place. Only thing is that with bad weather like rain you may get loud sound crackles and pops and even a lost image for a few seconds at a time occasionally every now and then but not to often to the point where it wouldn't be watchable or irritating.

So does a picture appear on your TV at all?

Is the picture still okay enough like i described above?
If it is then a digital set top box should still work.

For instance, on my Sony TV if i use analog reception i get a lot of snow, lines, color distortion, banding, etc. Sometimes it is watchable but just barely and not without eye strain. I use a SD set-top box and the digital reception is excellent.

Just a word of warning, if your antenna is a small indoor type (is it?), it may not be able to pickup the frequencies that the digital signals are transmitted on.

Analogue reception does not mean a thing to digital reception, they use different towers.

I would just try it and see how it works, if it doesn't then get a better antenna, if it does then good for you, with reception like you are getting you need something better either way.

I get a lot better reception then that on mine with channel 7 and still it cuts out sometimes at night for some reason while the analogue reception stays the same. (This is with a roof top antenna though).

schplade, just because they use different towers doesn't mean that you can't compare the general signal strength at his location and the performance of the antenna. And the digital data signals are themselves modulated onto an analog carrier signal. Just because it says digital doesn't mean that a digital signal is transmitted.

Yep, adam93, looked at the pics the signal seems to be more than good enough for a digital set-top box. I don't think that mine is that good on some of the channels!

Anyway, now there is still the question what frequency bands that antenna can handle. It might be written on the antenna itself, see if it says VHF + UHF on there somewhere. If it lists both without any exceptions then it might be good.

As schplade said, i would get a box and see how it goes. They are cheap enough these days and you can get some as low as $50 that are reasonable. The one i have cost about $200 but that was about a year ago.

A friend of a friend asked me to help them setup their digial set-top box, so i gave them a hand. All they had was a cheapo indoor rabbit ear antenna but it worked perfectly, as some of the others have said give it a go.

cheers

ok, thanks guys for the help. My antenna says FM.VHF-UHF. I was going to grab one of these

I already have digital on my main tv (42" lcd) and yea the reception with that is great although it uses the roof's antenna.

*EDIT* or the other option is to put a antenna port in my room

My analog is rubbish, my digital is perfect. Everything I have seen and heard about using rabbit ears is very hit and miss.

Buy it and see what happens, worst case, get a new antenna line put in.

Friend of mine had me set-up their digital STB, he decided at the same time to change where he was going to receive his reception from (Canberra vs Wollongong towers).

He got up on the roof and swung the antenna around 180 degrees to face where he "thought" the Wollongong towers were, straight up we had perfect digital reception, analogue reception was not to be seen though, he kept adjusting the position until we got analogue reception. In doing this he swung the antenna around completely and we still had perfect digital reception (When infact the antenna was anywhere up to 160-180 degrees in the opposite direction).

In a lot of cases digital actually uses the same towers as analogue folks.
I mean why would the tv companies go to the expense of putting up a new mast and new building when the have a perfectly acceptable mast already up that they can hang the transmitter antennas off.
The only time they would put up new masts is to fill in a black spot that analogue used to cover but digital does not due to signal absorption or blocking.
As far as reception antennas go have a read of the dvbt forums for whats a good external for your area.
http://www.dtvforum.info/
Look in the regional section for details.
I had to change my roof antenna to get digital reception despite having very good analogue. For my area I went with one of the Fracarro (LP45HV from memory) antennas as it was available locally.
Also check whether you need horizontal or vertical polarisation.

hmm, thanks guys

to osama_bin_athlon i would rather buy the digital set top box for that price, because then i will have digital channels (eg. abc2 and channel guides)

I get all that, and a remote! (the channel guides are fairly useless) not having an actual TV, it's a very cheap option.
the rooftop aerial only picks up 2x stations - with my old analog TV card, it would pick up everything brilliantly....
the $40 DSE job is what was highly recommended to me.
seeing I already had a 22" monitor, it's a pretty good result for around $100 all up - how much would the equivalent television cost me?

I've been studying this lately.

It's kind of interesting.

If you have a good quality (50db Carrier/Noise) analogue signal, it's more than enough for digital (which requires approx 40db Carrier/Noise).

It's actually possible to overdrive a digital system with a good quality analogue system..

Interesting stuff really..
