I have used a separate bias tee and power supply. Used a 5.2V supply from my Amazon Kindle.
Didn’t want my $$$ receiver to be at the mercy of an electrostatic discharge or a short in the cable. I also added a gas discharge arrester inside the house.
After a while, because by coax cable is long, I was annoyed by the voltage drop on that cable and the fact that I needed to be careful of how much voltage I was sending on that cable. So I have modded the LNB with a 5.0V power regulator and I am feeding it from house end with 7.5V.
