I have. 378ts and just purchased a Wineguard Pathway X2. I tried to use the cable port on the right side compartment next to the door but could not figure out where it goes inside. I would have thought it would have been t'ed into the left rear cable port that is in the power cable door. Nope not the case, so I used the normal cable connector in the rear. I added a T right behind the TV switch box in the front upper right compartment. That way I don't have to remove the coax from the box when I want to go to the dish. So now the coax goes from the dish through the MH and I run the coax from the T behind the tv switch box to the satellite receiver that sits on a small table right behind the passenger seat. I installed a HDMI cable to the back of the TV, plug in the cable and I am all set with HD Satallite TV.
To get to the back of the TV you will have to remove the top and bottom screws on the TV brackets. I have had problems in the past with the input cables on the TV getting pulled part way out with the MH bouncing down the road, so I use a piece of good sticky foil tape and taped them the the TV so they can!t work free. The nice thing about the Pathway x2 is it is powered through the coax so no other power needs to go to the dish. Someday maybe Georgetown will get with the times and set up with
HD type cables.
