addition...The C-Band LNB usually has a skew marks or an arrow on them. Some LNB"s seem to be off by 90 degrees
The 621 is usually true and has an arrow at the end...line that up with "0" (or an approx)
The 421 seems to be off by 90 degrees so line it up for 9:00 or 3:00. The 421 has skew markings on the end of the LNB
The Eagle Aspen stacked LNB seems to be right on
cool deal Ice, I did move the dish/lnb like you said and walla, 121w channels began to appear on the cband side. Doing a blind scan to see what I can find there lol.
Btw: I am using the 621-2 w/o the jumper, and a cw-800s.
