To the OP. Instructions from my installer were that I should make the coax connection to the splitter, the last thing I do. "Don't connect a cable here and have it unconnected on the other end. It will disable your MRV." But he definitely said all I have to do is hook up a cable to the splitter. I think once they hook up MRV and essentially put the coax on the network, the ends have to have terminators on them if they aren't hooked up to something.
Regarding the blue barrels vs white barrels:
I try to use the best materials I can (within reason). If a white barrel works.... fine, but for how long? No I don't mean the barrel will degrade over time. But as we change things, we add connections, add cable, change this, modify that.... The point is that there are so many "pieces" (whether cable, connectors, splitters, etc) between the dish and the receiver, that I feel it's important to use good "pieces" wherever and whenever I can. One white connector in your wall outlet may or may not be a big deal, but several on that cable run may degrade signal noticeably enough to affect performance.
I used quad shield cable. Was it overkill? Would a good, standard RG6 have worked? Maybe? Probably? But I knew I was going to be crossing electrical lines and/or paralleling them a bit closer than I'd like. (I like to keep 18" away from electrical lines if I have to run parallel to them. I cross at 90 degrees and they don't touch). Would an installer use quad shield? I doubt any of them would use it normally. My point (and I really do have one) is to use the best you can wherever and whenever you can so you minimize potential problems. There is a "practicality" factor that comes into play though. What you would LIKE and what's PRACTICAL may be 2 different things.
