Ahh ha! Something I can actually assist with!
This is provided the PayTV you have is satellite and not cable. If it's cable you have, your going to have some issues getting a satellite box. The reason is
the pay tv companies will not subscribe to a mobile home generally, too hard to get money out of people who move all the time. You need a fixed address and a service at that address to accomplish this.
If you have Satellite PayTV at home (ie..Foxtel or Austar) then all you need is a dish with an LNB (they can be sourced from fleabay)
A LNB is the low noise block which is responsible for the dish receiving the signal. With the LNB you need to ensure it is set to the correct LNB frequency of Austar/Foxtel if you are going to use it. If not, you won't get any signal.
Place a pole mount which can be swiveled but also with a lock bolt in it. This way once the signal is found, you can tighten the bolt so you don't lose the signal. I know with the Austar boxes you can go into the settings - installation and see a signal meter on their showing the BER and Signal Strength. BER shouldn't ever get over around 80. This way one person can slowly move the dish left/right to get the signal watching the strength on the tv.
If you can a small crate then I have seen people use these to attach the dish to also, however last one the guy was driving a modified bus, so he had all the room in the world for storage of it!
Generally Foxtel and Austar Signals on the Eastern Coast of Aus, angle of the dish doesn't change, but the direction depending on where you are in the country.
An 80 cm dish will pretty much go anywhere these days in Aus for most parts on the eastern coast including Darwin.
A good website for all information about Austar/Foxtel for PayTV spec is
http://www.austech.info and generally has all the information surrounding the different subscription tv services in Aus.
