I am considering the purchase of a larger satellite dish (33"-39") to both improve reception quality of standard DishNetwork channels, but also to experiment with multi-lnb setups, international channels, etc... If I want to use the dish for my normal DishNetwork reception also, I figure I'll need a DSS dual-LNB to pickup the 110/119 satellites; the arms on these larger dishes and the brackets used to secure the LNB don't look like they'll work with the standard DishNetwork LNBs. Also, if I do use the generic, single-head DSS LNB, will I need some sort of switch to make this work with my Dish DVR 625 receiver? Currently, I use the DishPro500 dish with the twin-head dual LNB and do not need any external switching device. Anyone had experience with this or have any advice? If so, is there a particular brand/model of dish and/or LNBs that anyone can recommend. Thanks.
