Hi! I have a question.
Both feedhorns stay at same height?? I have INSAT 4A as prime and IS20 as side LNB. When few TPs get signal others donr. When others get, the first set doesn't! I had to set the side LNB feedhorm about 2.5 inches higher than prime feedhorn. Pictures posted show no such difference..
have you tried to make such difference in height and check the signal availability?
