CCTV Balun for Satellite Signal?

[68sting]

I have some cat5 and 6 ran to my daughters room. I would like to add a Directv HD receiver to that room and I was wondering if these cheap cctv baluns would get the signal from the switch to the receiver.

DirecTV does make pretty good use of that coax cable, including running multiple LNB's and MoCA ethernet over the same wire... so it might be a stretch, but I'd try a set of these and test by moving an existing receiver in there before ordering a new one. Make sure ethernet and video all work.

While I haven't tried, I would find it highly unlikely that it would work.

The coax cable also provides DC power to the LNB and switches between 13V and 18V to select the polarization of the received signals to switch between them (odd/even in DirecTV terms). Without this you lose half the satellite since the baluns aren't going to pass the voltage.

Further reading also indicated that the frequency band in use won't pass through typical baluns and cat-5.(DirecTV technical forum)

Thanks for the help. Looks like I need to go another route.
