Digital camera Review: Does What It Is Supposed To Do
Summary: 4 Stars
DC Blocks used to be easy to find at your corner Radio Shack. No more! I found this one on Amazon for a decent price and bought it. It isn't the highest quality DC Block available on the internet, but it is of superior quality to the Radio Shack units I used to buy before RS stopped selling them.
If you have a coax cable connected to your TV or other electronics equipment and that coax has any DC power running through it at any point in the configuration, this is a good safety feature to protect your expensive electronics. Also, if you have a pre-amp on a coax line to your antenna and decide you need a splitter off of that coax line (between the pre-amp and its power supply) to go to another room, installing a DC Block on the split off line is necessary for the system to work properly and for your equipment in the other room to be protected against stray voltage.
BTW, these DC Blocks are bidirectional, so it doesn't matter which end of it is facing upstream or downstream.
