This is a pic of MY Humax transponder details. I haven't been able to go over to neighbour's house today, will do tomorrow.
He only has one lead into back of Humax. There are 4 leads entering the house, so I'll check where they are coming from.
We are in 24500 Razac d'Eymet. I don't know for sure his dish size.
Mine is 80cm, it is on a pole in the ground, did it myself in 2011, good alignment. Fitted new LNB about a year ago when it was struggling in rail. Now it can really tip down and it is still ok.
