Advertisements Gang - I've been running my Bolt and Mini just fine with a MoCA connection. There is an upstairs guest room with a coax connection but no TV right now. My wife wants our infrequent overnight company to be able to watch TV in their room. I don't want to invest in another Mini but she is willing to go to our local TWC office and get an HD box for a couple of days when needed (less the $0.50/day charge). My question is will the TWC HD box be able to coexist on this setup? I tried to supply a diagram but it was a *.doc and I couldn't convert it to a JPG file. (My MS Word is very old.) There are 2 other coax runs coming in from the outside - one goes to the room with the Mini and the other goes to the guest room where we want to run the TWC HD box. I have a POE filter where the cable comes into the house. I am not using a Tuning Adapter. I have no amplifiers. Would I need a POE filter prior to the HD box? Thanks!
