I just picked up a G.I. 450i analog receiver. I see that there are 2 lnb inputs on the back one is: c/h the other k/u. I understand what they're for, but my question is: if I slave it to my 2700R. Do I have to have a splitter inbetween the 2700 and the 450i, so that I can connect the 2 lines from the output of the splitter into each c/ku input of the 450i. I am currently using a G.I. 2400R and there is only one input on the back.
