C120 LNB skew...

[SatAdam]

My Direc PC dish won't skew enough. It goes to 40, and I need 43.6 There is another set of holes in the LNB, if I move the LNB to the next set of holes, how much does it affect the skew I need to set on the dish?

Thanks!

If you turn the LNB 90 degrees on the C-120, your polarity will change. I'm not familiar with that dish, but is it possible to turn the feedhorn slightly one way or the other?

na, that's the problem... the feedhorn bolts solidly to the arm as the feed is tweaked to the dish shape. I finally found somewhat of a sweet spot and get 60% quality on 12035 on G10R. It'd be better if I could get that extra skew...

could you put the lnb in the other holes then skew the dish back to get you 43?

 

[SatAdam]

the other holes don't match the pattern on the LNB... The 40 the dish does is close enough, I can tweak out 75 quality on TP 12035, that's good enough
