Hi there,

I have just moved into a new house in Wellington city that has several tv coax outlets (the pin / screw in type). There is a Sky satellite and a Sky UHF aerial on the roof. The landlord said the house was all recently wired and that Sky would work.

I plugged in my Sony Bravia tv with built in Freeview via a coax outlet in the lounge. I bought an adapter for the coax cable to fit into the rf input on the TV. Then I ran digital auto tuning on the tv and it picked up 4 channels: TV3, TV3+1, C4 and C42. I was disappointed though as I thought with the satellite I would have been able to pick up everything.

There is a TV outlet in every room and a couple in the lounge so there is at least 5 in the house. I'm not sure but is this a complicated thing to do? Could something have gone wrong with that? I'm not sure if our satellite is setup right.

Any help would be appreciated.

Thanks.

You sound like you have your transmision types backward.

Theres 2 signals for freeview. DVB-S (think of it as satelite) and DVB-T (think of it as tv antenna) which is the HD signals.

It sounds like you just plugged yout sat dish with an Fconnector adaptor into an RF in. This isn't going to work.

Your Tv has a inbuilt UHF (-T) receiver, and needs to be connected to the UHF aerial. The fact its getting 3 at present may likely be a false indication of a strong UHF signal in the area for those.

I see.

Every outlet in the house is an f-connector (satellite?) so I'm not sure how I could correctly hook the tv to the aerial.

I've tried some rabbit ears with a uhf loop plugged directly into the tv and no channels were picked up with the digital auto tuning, with analog tuning some channels picked up but none were clear.

A good indicator if you will get UHF freeview is if you can receive prime on analogue mode. This is the closest channel to the BAND that Freeview uses. So if the image is clear, the signal for digital is likely to be.
Rabbit ears often do the trick however it sounds like yours may not have. (they can be full band, try shortening the length of them)

F connectors are perferred in Sat connections as the core of the coax becomes the pin and is directly attached to the equipment for minimal loss http://en.wikipedia.org/wiki/File:F_Connector.jpg

Your standard UHF antenna cable should look like this http://en.wikipedia.org/wiki/File:Bellingleeconnector.jpg

And is often cabled throughout older buildings so analogue tvs can be used all over the place. Only more recently has Sat tv become a common point install. As it is harder to share a single sat dish with multiple outlets without issues.

The other flipside may be the multiple transmitters in welly. Others can confirm but depending on location 1 transmitter is likely better than the other for Digital reception.

Hmm I would also confirm that they are not Telstra cable rather then being connected to the sky dish. Telstra cable connections also use F type connectors.
If you are getting 1,2 3 it might be Telstra cable as it is possible to pick them up on analogue however you will get a visit from them if you leave it connected as it does terrible things to the cable network.
I think either you need to ask the old owners via the real-estate agent what they were using or get someone in to have a look and tell you what is currently setup and if necessary change it to how you want it.

Right yeah I think I will have to ask the owners.

I tried a Sky decoder from my last flat and all I got was a "Rain Fade" message. I searched on here about that and followed the instructions about changing the LNB setting but still got the Rain Fade message.

I was hoping I might be able to get something to work without bothering the landlord but it's probably best to find out exactly what they set up.

Correct. The LNB settings open a can of worms of their own.

Usually (not ideal truth case) the single head ones are 11.300, and the new sky dual head sharps are 10.750

Is there any other reason that would have stopped Sky from working?
Satellite set up wrong or something?

I'm pretty confused now that the Sky didnt work and the Freeview kind of did even though it shouldn't have?

It is entirely possible the short lenght of cable you had attached was working like an antenna for the tv.
Often signal can be had by jamming your finger in the hole and touching only the centre :)

As for the sky issue. LNBs can die if they are old. Or as stated it may infact be a cable connection not sky.

Once you find out be sure to label the outlets :)

Sky, Cable, UHF or similar.

Cable as in Telstra Clear Saturn?
The outlet says TV on it, I just assumed it was for Sky and also thought Freeview would work through Satellite too.

Would it be a good idea to try the tv on all the outlets as they might be different?

Thanks for the help.

Sure. Might just work in your favor.

The norm for home cabling is to have a UHF antenna, Split it to around 4 points and lead them to other rooms for standard tvs to use. You can do this with UHF with ease as it is like a single band of signal that your TV plucks out active channels from. So each room can have a different channel on etc.

Sat is a little different. The LNB needs power to work. And the signal can have a Horizontal/Verticle signal mux to it. So usually only 1 decoder is advised. And due to the frequency signal loss is not wanted. If you have more than 2 decoders on the same dish, if you change to say SBS australia, sky will die. As it is on a different transponder (or signal source) polarity.

Cable (saturn) is similar. Single muxed signal from the street goes to a decover unit.

To get sky/Cable to the rest of the house, sometimes you can feed it back OUT of their UHF outputs, back into the house cabling.. joining the standard UHF signal and let you tune it on analogue tvs elsewhere into it as if it was a tv broadcast.

But thats getting a little techincal.

Sounds to me like you plugged into a Sky Satellite socket. If there's Sky dish and a UHF antenna on the roof and the house was recently rewired I would guess the UHF Antenna is not connected. If there is only single socket F connector outlets and the previous occupiers had Sky Satellite then that would be the clincher (no UHF). Your Sky should work OK but as others have said your only picking up some stations on Freeview Terrestrial because the coax and sky dish are providing just enough signal for those stations to tune. You need to check if the UHF Antenna is connected to any of the wall sockets. Your TV tunes Freeview UHF Terrestrial, not Freeview Satellite.

You're not in an apartment complex are you?

Nope not an apartment. It's a stand alone house but it is next to apartments. The house is very newly refurbished. The wiring must be brand new.

I took some photo's this morning. I'll post them soon.
