OK. As you can see, there are various ways to wire and setup an RV. Therefore there are various answers to your question.
There is not a yes or nno answer to this.
1. Do you havew a "Sat/Tripod" in in the wet bay? If so, where does it terminate? Do you have an AB switch or two dangling cables?
- We have a Tripod (Sat.) in and a roof Sat to an A/B switch. This is all RG6. This allows me to use the roof (Winegard Mission Raod Trip) sat or an external (We have a Tailgater).
2. Can you use the Cable in?
- Maybe. You would need to add an A/B switch inside, before an AV switch, to bypass your cable connection or you can manually move the cable inside. Now that is just the physical connection. The Tailgater also relies on the coax for power, so you can throw it our wherever you want/need. With RG6 and I have heard of some running upto 150' of coax, with successful signal. I have only used 100'. If the coax is not RG6 and this includes coax you would use in the path, inside your RV, you may find signal loss or more likely not enough power to the Tailgater for it to properly run itself.
