I am currently a Voom customer and have decided to go with D. I have purchased the HD DVR and triple LNB dish and will be installing it tomorrow.(Thanks Value Electronics for your quick shipment and best price!). I plan to use the Voom OTA antenna because I get all my locals without any problems. On my Voom set-up the OTA cable and satellite cable are are routed into a Winegard Satelite off-air combiner so I have one cable going into the Voom STB diplexer. On the D HD DVR, there is a separate hook-up for the OTA. My question is... do I need to run a separate cable for the OTA antenna or can I use the same set up? The V STB has the diplexer mounted on the back so I doubt I can use it but can I buy a diplexer from Radio Shack and still use the same set up? Is it best to run a separate cable anyway? Lastly, I have found out the some of the OTA antennas supplied by V get their power from the diplexer. If I buy a diplexer, will have to also purchase a power inserter? Does the D HD DVR have a power supply built in for the OTA antenna? Any help would be much appreciated.
