[QUOTE="jeallen01, post: 1024697, member: 176704"] May I say that I think there is something not quite as clear in the first post as it could be, and that one thing is missing: Instructions 3 to 5 say this: [B]3/ Motor set at the correct Elevation for your location for maximum signal at your reference satellite,[/B] [I](4/ Motor at zero on the scale when aimed at your reference satellite,)[/I] [B]5/ Dish Declination set for maximum signal at your reference satellite,[/B] The thing that is missing (at least for off-set dishes) is reference to the "Dish Off-set angle", i.e. the angle between the axis of the dish and the centre of beam seen by the LNB, and the relationship between that and motor elevation & dish declination, and this is discussed (probably amongst many other places) [URL='https://www.satellites.co.uk/forums/threads/declination-angle.166531/']here[/URL]. And that's an area I had a lot of trouble with in setting up the steerable Triax early last year (not helped by the fact there are two separate dish declination scales on the bracket at the back - one for low latitudes and one for high latitudes!). FWIW (after instruction 4) when doing that I used a fairly simple sat beeper to get some sort of "signal" from a sat that I was looking for, and then with the Rx fed to a monitor near the dish (all at ground level!) I began to see actual broken up images (digital is like that!) pop up, and I adjusted the dish declination by loosening the declination adjustment bolts and tipping the dish edge up and down until the image stabilized - problem is that there is only a minute angle (couple of degrees or so) of such adjustment between no signal and good signal, and then you have to be able to hold it in the best place for the latter whilst tightening up the declination adjustment bolts!
