We live in an area of Chch that does not get a good TV signal, and we have sky digital. In the living room we have a sky socket in the wall and an aerial in & aerial out socket / plug. (although we don't have an aerial on the roof - just the sky dish)

Currently we have the sky decoder in the living room and the sky man ran a cable from the back of the decoder to the 'aerial out' socket and we have a TV in the bedroom that we plug into the TV aerial socket in the wall and we can get all the same Sky Chanels that we get in the living room. but we can only watch the same chanels as in the living room.

We are thinking of getting the 'free to air' digital set box for the bedroom, so that we can watch different programs, but also still be able to watch all the sky programs in the bedroom.
We can buy a 'splitter' plug with 2 plugs on it from somewhere like Dick Smiths and we can plug that into the sky aerial plug in the living room then from one side run the main sky lead to the decoder and on the other run a small cable to the 'aerial out' plug and that will take the signal to the bedroom. Then I believe we can plug in the digital set box in the bedroom to get the free to air TV, but this will diminish the quality of the signal - is this correct?

We would probably also need another splitter for the aerial out socket in the living room? - so we can connect the cable from the decoder to the aerial out plug - enabling us to also get the Sky chanels in the bedroom as we currently do? but we are only able to have 1 cable coming out of the socket on the bedroom and we would need it to plug into the free to air digital box, but also get the sky chanels from the living room decoder - confused? I am!

The more I think about it, the more I think it probably can't be done...... but I am not a quitter!
so if anyone has any suggestions as to how it might be able to work I'd be much appreciated.

It may be able to tbe achieved with the same dish, just not right now with the current setup.  As I understand it, the polarity is a current issue in that Sky & Freeview use opposing polarities.  This is being addressed & will allow you in the future to use 1 dish for both Sky & Freeview. 

As for the cabling, best to google search GZ for the recent posts on this topic.

forgetting, for the moment, the extra channels available on freeview have you considered renting an additional decoder from SKY?

For a $100 install and $25 a month you can get a second decoder which allows you to watch any of the sky channels in a second room.  Add those up and it costs $400 for the first year, $300 in the second year, etc...

To install freeview you are going to have to buy a decoder $300 and splitters/cables etc and you may possibly need an LNB upgrade.

the SKY option may cost you approx. double over the two years but the return on investment might be better given access to more channels...

note: i don't have sky myself, i only have freeview.  if i was already paying for SKY I think i would go for the second decoder (or look at the mysky option if you can multiroom it)

Yes you can do what you want with a simple splitter (DSE L4036) although you will need to wait till Sky move to Hpol on the 1st of August to make it work properly, it will not easily work until that happens.

As there is a cable already run from the lounge to the bedroom you have two options, either run a second cable for the satellite feed to the bedroom or use a pair of diplexers (DSE L4696). You will also need to be able to make up some suitable cables with Fconnectors.

There is a loss involved with using both the splitters and diplexers, however unless you have 60m or more of cable between the dish and anyone STB then it should not be an issue. Also be aware that the splitter I indicated above will pass power only on one leg, this is not a real problem other than the fact that the STB connected to that leg will need to be on for the other STB to work as DC has to pass from one of the STBs to the dish to power the LNB.

Essentially to use the diplexer option, take the feed from the dish to the sky box, connect it to the common feed of the splitter, have one side of the splitter go to the Sky box (the one that has DC pass), the other output of the splitter goes to the sat port of the diplexer, the RF out of the Sky box goes to the TV/V/UHF port of the diplexer, and the common goes to the bedroom via the cable. In the bedroom use the 2nd diplexer to reverse this ensuring the sat port goes to the LNB input of the FTA STB and the TV/V/UHF port goes to the TV.
