I want to put a satellite dish by my shop for football games and etc. I have a Dishnetwork Super Dish with the 110, 119, and 129 degree LNB'S or triple. I would take one receiver from the house. My question is that I have an extra Dish 500 (20") with the double lnb's 110 and 119. Could I put another lnb 129 degree on that size of dish? I want the 129 because that is the one for local programing. Are all the Dishnetwork lnb's the same or they different for the different satellites? The shop is far from the house, maybe 5 to 600 feet. Thanks
