I have a few lnbs kicking around, currently have a universal and a circular on my 30" wineguard. I also have a diseq switch, but it interferes with my universal and switching is tempermental (to say the least a big pain in the rear). Has anyone used a signal combiner, I think echostar makes one. and how do they work? What could be my other options to switch between the 2 lnbs other than a "AB switch" with a whole lot of Coax cable.
