Just took delivery of a 2014 Rockwood 8310SS. I plan to take my Directv Genie(HR-44) and Client with me when we go to the Gulf coast in October. The system is connected together using the SWiM technology from DTV. For it to work in the new TT I had to replace all of the connectors related to the satellite. Actually, while I was at it I replaced them all.
If you look at the insulator in the center of all the connectors in the TT, they are probably clear/white as mine were. For my installation these are not acceptable because they are not designed for high frequency applications. Local TV - cable no problem but because the SWM freqs. are near 2 ghz they do not pass the signal very well. Consequently, a connector with any color other than the clear/white is good. The ones I installed have BLUE insulators. These have a frequency range of zero to 3 ghz.
Do not know what configuration you are trying to install, but changing the connectors can only help the cause.
