OK! After studying the "LNB and Multiswitch FAQ's" and several other posts on multiswitch requirements I've managed to have gotten lost in the LNB/Multiswitch Jungle. My question has to do with adding a new HR10-250 to my present system: I've been using an inside "Terk 2 IN 4 OUT Multiswitch" - two outputs to feed my Philips DirecTiVo AND for awhile, one output to a bedroom DirecTV receiver. (Which I dropped sometime back - Who can ever again watch regular TV after using TiVo?) They're coming out Monday, Jan. 9th. to install a new HR10-250 with a DirecTV Multi-Satellite antenna. Per the DTV downloaded Installation Manual, the antenna comes with "Integrated Triple LNB and Built-in Multi-Switch." Is it possible to use my original two RG-6 cables from that antenna's multiswitch into the Terk and then use it's 4 outputs - two for the DirecTiVo AND two for the new HR10-250? I ask, because while some installers appear knowledgeable, others are not. On two separate occasions for our two daughter's DirecTV install's in two different communities, hundred's of miles apart, each installer used one existing "Cable TV" RG-59 cable and one new RG-6 cable! Rather than waste the cable ??? Sorry to be so dumb on both the subject and finding my way around the forest!
