Well, depending on where you're at (I'm guessing you're either in the Omaha or Lincoln "area"). That is, you get your locals from either Omaha on Dish or from Lincoln/Kearney/Hastings. If that is the case, then we are *supposed* to be an eastern arc market, meaning that your HD locals will be on 61.5 and you won't need 129. Now, it looks like they may be putting some additional locals up on 129 for us, but if Dish does what is expected, those will also be available on 61.5 and you won't need 129. Nothing is saying you can't put up another dish to pick up 129 if you want to, but it looks like at this time Dish won't require it (nor will you need it).
I'm hoping they get those locals up soon. I've only seen the uplink listing on Ciel-2 for the NBC and Fox locals (I'm an hour west of Lincoln, BTW), but I've only been looking at this site for about a week. Hopefully, they put them on 61.5 soon. I'm sick of NBC and Fox in SD while I'm hearing that DirecTV has them.
