Dish LNB Compatibility

I have a few ideas to attach the Dish LNB to my FTA Dish, and motor the dish over to the location I need it too. :)
You'll probably just want to stick with the dedicated Dish 500 Plus, the receiver is going to need to "see" 110 or 119 (I forget which one) along with 118.7 at most times to keep its guide updated and its authorization. I don't think it will like just "seeing" 119/118.7 when you have your movable dish over that way.
