Your welcome for the input. As far as that looped cable,I'm not sure what the heck it does! I would be willing to bet someone on this site will know ( their are some really sharp folks on this form ). Just to the right of that looped cable is another outlet the top is a 12 volt outlet just below that there is a cable connection.there is a cable from there to the back of the tv. We changed the tv mount to a lockable/adjustable bracket,we changed that cable to one that has 90 degree ends, the bracket takes the tv closer to the wall. Oh yea, on that same outlet there is a small push button it is for the antenna booster. A green light will show when it on,it has to be off when you hook up to outside cable. The Furrion brand tv is not the best,ours died with in a year. We were at my kid brothers house just outside of Brownwood Tx. when it died.Went to Wal-Mart and bought a Vizio 24 inch smart tv for about $100.00. Darn thing has a much better picture a costs a lot less. Jayco did warranty it so we just put it in the guest room closet. Be well and enjoy the neck out of HB.
