very sorry to use this thread, but I had no permission to start a new one?!
You have to build up a number of posts before you can start a new thread. There is a note in my sig below for more details.
Also this post should probably be in the Sydney Viewers
forum, as it relates to reception (as well as, in a way, to STBs).

I went up the roof and tried to disconnect the cable (which I think goes to foxtel socket) from the satellite dish and connect it to the aerial antenna. Unfortunately this was not possible, because the space was so narrow under the roof and I think the cable is directly connected to the dish outside the roof? Would this work?
It may work (a cable is a cable), but I believe you are not allowed to interfere with the Foxtel installation on your premise. They put it in, it worked, if someone else needs it later, it still needs to work.

A friend told me I could buy a cheap SD set top box and connect it to the foxtel socket. And leave it connected to the sat dish. And then I could watch the free FTA channels that way. Is that true?
No, that is very unlikely to work. The only way something would come through like that is simply if the cable and satellite dish were acting a a very basic antenna, so bringing in some FTA reception. As the satellite system is most likely installed with good quality shielded coax, 'accidental' pickup is unlikely.
Your best option is to try and use the roof antenna (television antenna); you may be able to try with an indoor antenna, but you would need to be close to the transmitters.
Where are you located?
I really think you should get your post count up to 5, then make a new thread on this under the Sydney Viewers Forum. Copy and paste your existing text over to the new post. And make a New Topic, rather than just tagging this to the end of the large existing 'Get The Best Reception' post.
