Well ya have to be a patient man to do this because it's a bit more involved than just tuning in a round dish.
Assuming you have the oval slimline dish with the single swm wire you start off like you would with a round dish and that is to locate sat 101w once you have 101 locked in around 95% or higher you just tweak your tilt and skew until 119 and the rest of the sats will fall right in.
Sounds easy but it can be very time consuming or it could take no time at all.
Just depends on yer luck.
I suggest getting a dish pointing app on your phone and make sure your dish is perfectly level before starting. The high def dish is way more sensitive to being off level than the round dish.
As for me I am saving my milk money for the Winegaurd Travler Auto HD dish.
