Now if in place of Primary SW64 in this diagram we use a 4x1 diseqc, then technically it can feed a VP-1020 or Nexus etc. Since diseqc will be connected to pass thru port of the splitter, it should be as good as connecting it straight to LNB output!
This way the Secondary SW64 can continue to feed the subscribed IRDs (upto 4 receivers) while the 4X1 diseqc can be used to view FTA on a PC.
Any thoughts? Also if this would work, where do you find the Feed-Through Loads?
Thanks.
