Hi, I just had my shaw direct installed with two separate dishes but I can not watch both with my current connection. First, I used a small switch that reads 0/22khz and each input for the LNB reads 22khz on one side and 0Khz on the other side and is 950-2150mhz. I can only watch the satellite connected to the 0 khz input so I figured I had the wrong switch. Today I tried Perfect Vision 22khz tone switch that the retailer claims works on directv AND shaw direct, but with this one I can not see neither! The installer told me that I need a switch with external power but I don't want to spend any more money until I'm sure what I need. Please help! Thank you.
