I currenty have a dual LNB with a feed running to my two recievers. I also use and off air antenna. I have bought a new oval dish in order to get local channels for the Tivo and will soon add a HD reciever to my Home theater.
My qeustion is do I have to run extra line from each LNB on new Oval Dish to each reciever. Also If I setup the 3rd LNB which would make total of six lines. Could I use a 3 to 4 muliplexer and only feed one cable to each reciever and then break ten out. The 3 to 4 I have seen Label 2 LNB and 1 ANT on it.
