You aim at satellite 119. The trick is to insure that the 119 LNBF is being selected. The Dish 500 Pro has a built it switch and without a controlling 22 KHz tone, either cable can be connected to either LNBF.
Always make sure the mast is perfectly vertical. An adjustable leg tripod helps this a lot.
The hardest alignment in the azimuth because the signal focus is no where you think it is by looking at the dish. Right now people look at my dish and shake their heads because it looks like the dish is aimed into the back of the trailer. With 138 Skew and 38 Elevation, the focus is off to the right of the trailer.
The metal dish will cause a deviation in a compass close to the dish, upward of 10-20 degrees.
I have a lot of info on this at
