got my voom today - the installer did not use a diplexer - but he did use the stealth antenna - i had to goto work so - i only had a half hour to look at it. i am happy that i am getting all my locals except WB. I live in north jersey ( nutley). i will get home at 9:30 to see what voom is really about. My installer did not install a phone line - is this a problem? how does my receiver get updates?
