if you managed to find optus B3 your intelsat8 should be easy to find too. stand behind the dish and move it to ur right hand side a few cms and then change elevation as in point it "up" by made 7 ~ 10 degrees..if u have a sat finder it should be easy if i found it with FTA box signal i am sure u can too! so RIGHT FROM B3 OPTUS POSITION AND UP!
