We have an austar box at home which we use only for access to free to air channels. We bought second hand satelite dish and sat finder recently so we can take austar away with us in van. But for some reason it will not find a signal. I use cords straight from the dish to the austar box but it shows no signal. I've used sat finder and have dish in same position as one on my roof but still no signal. Even used a different lnb on dish in case that was the problem but nothing. Any suggestions?
