More info is needed. If your looking at getting a SWM5 or SWM3 LNB and already have a Slimline Dish up, then yes it is fairly straight forward to swap the LNB's..If you are looking for a fresh install from the mast up, why not take advantage of the "Free" Install and if curious, assist the tech. Anyways provide more info on what your trying to do and we can answer better.
