If your 27hfs is wired the same as mine. The satellite will not work using the outside jack next to the water hook-up. That jack is for cable tv hook up. When you are at a site that has cable tv you hook up to that jack and make sure the power buttom, (on the jack in the living room) is off. The signal will be distributed to the other two jacks in the bedroom and garage. If you are using the roof mounted antenna then you push the power button on to get tv reception.
I have read a thread on this forum that describes the difference between cable tv and the satellite hook-up. If I remember correctly cable is just a signal in and satellite sends power to the dish and receives a signal. I remember the thread had instructions on how to modify the wall plate in the living room so that all three would work. If I remember right "herk" posted pictures of the modification.
I run the satellite cable in a window to the receiver which is on the shelf at the end of the bed. Then run a cable from the receiver to the wall jack in the bedroom. That gives signal at the other two jacks.
I have not been on the roof yet. I am a little afraid to try it. I am 300lbs.
