The international
DTV dish is NOT pointing at T5, where VTV 4 is located. It is pointing to Galaxy 3C at 95deg W. If you want to use this dish for
VTV4, you will have to point it to T5 at 97W, elevation will be 1-2 deg lower as well, depending on where you are. The DTV switch most likely is not compatible with a FTA receiver either, so you have to connect the LNB directly to the receiver in this case.
Also, remember that if you do all the above things, your dish is no longer receiving DTV signal!
