[QUOTE="rolfw, post: 175232, member: 175057"] If you are going to have a coax run of 130 metres, then you will probably need a bigger dish than 80cm or a line amplifier (perhaps both), as the loss over that distance is quite high, even if using a larger core coax cable. If you use WF165 or similar, you would get a loss of between 17db and 26db (depending on frequency) over the 130 metres, so you need a pretty healthy launch level. Not sure how the voltage will cope over that distance, have never tried to power a DiseqC motor on that length of cable and of course a line amplifier would draw yet more. [/QUOTE]
