The one from my 622 just went through its' 2nd Michigan winter and the one from my 722 its' 1st (but it was a rough one). Both are running outside. No problems at all. Mine are both 24awg--one is 25', the other 30'. Used a 1" bit. Hope this helps.
Question is, can I plug the cord that is now going to TV 2 into the 211 and remove the 2nd tv feed line from the 722k?
I imagine everything is all melded together somewhere because I only have one line going to the 722k vs 1 line from the satelite and 1 line from the 2nd TV.
