I am trying to understand this QAM thing, I just moved to Las Vegas and desperately need my locals, I tried $40 rabbit ears and get 50-60 reception on most channels, I am trying to avoid putting an outdoor antenna up if at all possible. What is QAM and if I were to pay for basic basic cable from Cox can I just plug that into my Dish OTA spot and get OTA HD Locals? Otherwise what is a good outdoor antenna that I can diplex to both vip 622's? Any idea if Vegas will be on the list for 2008 hd locals??
