From what I've heard, I believe that there will be no Live TV on the EMB's because the aircraft is not big enough to accept the antenna that is fitted to the 73s. A smaller antenna would have to be fitted, which would reduce coverage even further. Seeing as how the larger antenna on the Boeing is struggling to pick anything up, there is no point putting it on the EMB.
As for why it was installed on anything in the first place, you may want to look to your illustrious leader whose initials may or may not be BG. LTV is his baby, and was installed after almost everybody else in the company suggested it wasn't the smartest move.
VB like to be innovative if nothing else. Shame the product is a joke......
