We are the proud owners of a new Gulfstream Innsbruck 298DBS. We are also new the RVing. I have learned a lot from lurking around on this site and so far have been able to handle, figure out all that has come up. Today though, when trying to hook up my Direct TV dish I found a question to pose to everybody. My trailer has coax jack on the outside to attach an external antenna or cable hook up. When trying to run my satellite cable thru this port I cannot get the receiver/signal meter to function. When I attach directly into the receiver, everything works...There is also an auxiliary jack on the door/awning side of the trailer that I am sure is just for attachment of an outside tv, etc. Any ideas as to why I cannot attach the satellite coax to the cable input jack and make it work? Will I have to install a 2nd outside jack and run coax inside the trailer to the tv location just for direct tv? I will call dealership tomorrow to ask also, but I wanted to see if anybody had any suggestions 1st.
