I just acquired a free VuCube portable satelite antenna. The book says the VuCube is powered from the satellite receiver through rg6 cable. Other documentation states that the D11 or D12 Directv Receiver are recommended for use with the VuCube. I measured the volts on the rg6 cable and it is only 50mv (millivolts) do it appears there is not enough volts out of the D12 to power anything. (I knew this already, but I wanted to measure to be sure. So my question is ... Should a power inserter be used with the VuCube? (like the one that is used to power a swm antenna? I did some searching on internet and could not find a definitive answer yet, so I thought I would ask here! Thanks in advance for any info anyone might have!
