I have a Terk 5/8 (Sat A 13V, 18V; Sat B 13V, 18V; UHF/VHF). I always had 4 different satellites and never understood that I was missing many of the channels. I have used DiSEqC switches but it seems like one of the inputs did not work. I finally figured out that these "4 input" switches are really only made for two satellites. Is there a switch that would allow 13V/18V for 4 or more satellites? Any help would be greatly appreciated. Thanks
