Hi guys, I just bought an indoor antenna and used it for freeview. Funny thing is I can get TVNZ 3 and bravo with very good quality but no TVNZ 1 and 2 at all. Any reason you think might be? Thanks.

That's odd. I've never heard of TVNZ 3! I know they have TVNZ 1 and 2 and 1+1 and 2+1 .... are you saying that their 2+1 = TVNZ 3?

Yes. You're using an indoor antenna and the TV3 MUX is the only one giving sufficient strength for decoding.

My mistake. It's TV3.

And your 2nd mistake is assuming an indoor antenna will work on every channel in your area by default. Obviously it won't. Maybe you could state your location and distance to transmitter.

Well, all channels are coming back with good quality and strength. I'm living in the location with direct sight of transmission tower. I did some research before getting indoor antenna and placed the antenna near the window. Thanks for finding my mistakes and assuming me knowing nothing before posting. It's really helpful.

Indoor aerials dont tend to work at all well with digital TV.

Unlike the old analog TV broadcasts, digital either works or doesnt work - its completely unforgiving.

In analog you could of course get anything between no picture at all and full on reception.

Also, unlike the old days where one channel was one channel, digital broadcasts using muxes (multiplexes).

That means that (simplifying it somewhat), one 'channel/mux' carries TVNZ channels, one carries Mediaworks (3/Bravo etc), etc etc.

So you might get one mux clearly and pick up TV1, TV2 etc, but not the rest.

Interesting as this has just started happening to me, I had perfect Freeview reception via an outside UHF aerial for years, then on Thursday TV1 and 2 started to suffer poor reception, while TV3 was fine. I checked and rechecked all cables and tested via Tivo and the TV direct, and even another TV as the outside aerial feeds 6 outlets (but only 1 is consistently used)., all the same poor reception. I can only assume (yes I know the danger of this) that the aerial has moved? and is no longer correctly aligned? or it has become faulty?, or third something has changed at the transmitting end (which I doubt) to cause this. I also tired an indoor aerial with no luck. Any ideas?

I'm in Dunedin (Top of St Clair)with direct unimpeded line of sight to mount Cargil.

YMMV and a bit OT, but just to share my story - Ive lived in a few different places around Auckland in the last few years and generally had no issues with getting all the freeview channels on an indoor aerial...

Of course it may be a different story outside of Auckland, but it works well for me.

Doing your best is much more important than being the best.

Irrespective of the lack of detail you provided if an indoor antenna doesn't work its always because of poor reception and those laws of physics that govern quadrature amplitude modulation reception. All indoor antennas aren't created equal though, some are designed using principles of physics related to receiving UHF signals and others aren't.

I get all channels fine with a short piece of wire jammed into the antenna socket. Indoor antennas can work fine, and usually will for digital if you can see the transmitter (I can when its not foggy out west) - HDMI cables near the antenna are one frequant cause of failure, Not seen it with ethernet but I guess it also could leak enough out to interfere with it.

Not all indoor antennae are created equal.

I couldn't get reception in the bedroom using an indoor antenna, until I got an amplified one optimised for UHF with (from memory) 43db or 53db of amplification. That works fine.

Wow, these have to be some of the rudest and most unhelpful replies I've seen on this forum, and to a guy politely asking a perfectly reasonable question. I'm surprised he stuck around to get the decent advice that followed.

To be honest I think that @PeterReader needs to start stepping in with some words of wisdom on DVB-T TV questions. There seem to a an awful lot all asking the same question.

I must say that as a regular GZ reader (and responder) I really like trying to help where I can - and also appreciate whatever help has been offered to me - thats the great thing about GZ.

Not getting at the OP in this case - But there seem to be an increasing number of posts from people that could easily google (or search this website) and find answers in about 5 seconds but seem either unable to work out how to use google or search geekzone - or just cant be bothered. I can therefore understand the sacrcasm in some of the responses above - though they are of course - somewhat impolite.

Only one conclusion could be drawn from the original question - poor reception. As thread progressed no information was ever supplied in regard to transmitter in question (all vary in power) or distance. Also no info on whether indoor was a yagi, loop, bunny ears or electronic panel type and whether it was even suitable for UHF frequencies. I could see no way to help apart from state the obvious.

Fully agreed, but there are more helpful ways to explain that. You have no idea what level of technical knowledge somebody has. It takes a certain amount of knowledge to even know what kind of details are relevant. And the guy who mocked him for spelling the channel name wrong (though I assume that was an attempt at a joke) really got things off to a bad start - there was no need to pile in.

Anyway, enough said by me on this - I hope cloudlover has sorted his issues.
