[QUOTE="Vipersan, post: 637002, member: 325666"] Hi Robbo ... I'm fairly convinced myself that the cable is the issue .. I have a small overlap where both dishes ...my triax and the the new 80cm dish can see the same sat (33 deg East) Comparing 2 signals from the same transponder Eurobird 3 (11596V) Shows around half as much signal on the same receiver ..coming from the 80cm dish on the long cable run. I must be losing quite a few db over the distance ...which I may well have underestimated at around 30mtrs total length .. ..It could indeed be closer to 35 >38 mtrs Its good quality double screened with a solid copper outer layer ...but that obviously is insufficient to compensate for the length of the run . It was an ambitious project ...and I was well aware of the possible failings before I took it on . For the most part it is useable ...but I'm going to have to try experimenting with line amplifiers I think ....assuming they will pass the motor control information ok.. Can you quote any figures at me regarding this setup .. For example db losses per 10mtre of cable .. and effectiveness and placing of line amplifiers etc.. rgds VS [/QUOTE]
