For those of us who need to get a high definition program that is stored or being broadcast from a satellite or cable receiver in one room to an HDTV in another room that may be at the other end of the house, simply using a long HDMI cable won't work due to signal loss. However, several manufacturers are now producing HDMI extenders that use Cat 5 (or Cat 6 if you like) cable. Some that I took a look at but chose not to review needed two Cat 5 cables, so I waited. Now, Centronics offers an extender that requires only one Cat 5 cable and will send 1080p up to 100 feet from the source to your HDTV. You plug a short HDMI cable from your satellite box into the Centronics transmitter and another short HDMI cable into the receiver and HDTV at the other end. Custom installers take note: You will want to have a couple of these in your van when you start on a project.
