Ive noticed that Satellites such as Galaxy 3C/C 95.0W, and Anik F1/C 107.3 have low Tp Frequencies starting at approx 3780 up to the 4500 range. When setting my Invacom QPH-031 in Antenna Settings for LNB Freq of 10750 , I get no signal on S and Q and can't scan in any channels. If I change the LNB Freq to 5150 I can see high S and Q signal levels but a Blind Scan does NOT work there either. Do you need a special LNB or Dish to bring in these Satellites with low Tp Frequencies?
