I'm curious how multiswitches work. I have a triple LNB (w/4 outputs) that was going to Samsonic ASK4485T 4x8 multiswitch. The input side has 2 inputs for the 101 sat & 2 for the 110/119 sat. I've been having problems with my R15 coming up w/ searching for sat signal intermittantly on the tuners. As a test, I took 2 of the inputs & ran them directly to my R15, and it seems to have resolved that issue, so I guess my multiswitch is the culprit. I left one of the 101 inputs & one of the 119/110 inputs on the multiswitch hoping the other receivers would still be functional. I am getting some of the channels, but not all. Also, can anybody recommend a new multiswitch (and where to get) to replace my current one? Also, after I install the new multiswitch, is it possible to place a 2nd multiswitch after it? I have 2 cable runs to my living room, and would like to split the signal in the living room to go to 2 dual tuner receivers. Thanks for your help.
