In light of my upcoming install, how should I prep my cable run, if at all? My home is newer (2005) and has RG6 run throughout. All of the runs terminate into a home run panel. I am anticipating a SWM install (I've ordered an HD DVR, two HD receivers and MRV). I have one unused coax that is on the second floor. I have already fished a line from the attic to that coax wall plate. Ideally, the single run from the dish will be coupled here with the existing coax run (possibly putting the PI here as an outlet is also available) to bring the signal back to my home run panel for distribution throughout the house. My question is should I prep for the install by going ahead and running the coax needed in the attic? If so, should I get coax that is already terminated at both ends (probably a 50' coil)? Let me say I am not averse to tipping and plan to have funds on hand whether I prep or not. I just want a smooth install as this has been a long time coming (which I will detail later once the install is done). Thanks!
