I have a pansat 2700a and i'm trying to hook up 110&119, currently I have a dual lnbf which I understand can only recieve one sat. seems like I need to buy another lnb, but my question is, do i need a switch or any additional equipment to attach it to the currently dish? or can I invest in a twin lnbf and receive both Sat. at the same time? thank you much for helping this poor blondie out.
