Yes, Nimq 1/3 are same location but if you go to:

and look at the freq of the transponder you see that the lower freq and high freq.
You probaby using the DSS LNB, you getting only the high freq.
If you use the Ku-LNBF linear LNBF you can get low freq and a big dish.
If you use a universal LNBF and at least 30" dish, you can both.
