These switches are not powered. The STB supplies the power when a satellite is selected. View attachment 138709 This is the switch I'm using. Getting a voltage reading at the port or at the LNBF would be hard to do since it only loses signal for a few seconds. I'd never have time to get the cable unhooked to check it. I noticed on Galaxy 17 when the wife's watching Light TV, every channel loses signal.
It doesn't happen on one polarity or the other all the time. At this point, I am open for suggestions on what powered switch would be the best option. I assume with a powered switch, all ports would set up using a 22khz tone??
Is that switch outside?
