I need some help. I would like to have 6 receivers at my house...or at least 4. I currently have a Dish 500 and it has the Large LNB with only 2 wires coming off of it. Currently I have only 2 receivers installed...and they just take one wire each. Is there a way to install 6 or at least four without installing a separate dish? Do I need to change out the LNB? Please be basic in your answers, as I am pretty clueless. Thanks so much!
