I am in South Africa and aiming at Pas 7/10. I get excellent signal strength (80-90%) but poor quality levels, as bad as 0-5% on some transponders but up to 50% on others. This is with a 1.8m mesh dish (about 6' ?) and a 17' LNB. I have the same problem with a 2.4m mesh dish (same LNB) aiming at BadrC (26.2E). Please advise.
