Yes there is a lot of problems with the TI at C Band and the Wimax uses a frequency that upsets the C Band carriers , we have always seen lots of issues in the lower Bands , with Adaptive coding and higher QPSK it makes sense to move to Ku Band DVBS2 , you would not go far wrong moving to W3a or Telstar 11 and converting your C Band systems to Ku for a peacefull life , if you like to know more mail me Anthony@bentleywalker.com

What exactly do you see? What is the frequency you are trying to work and what do you experience?
