  I wanted a tv antenna connection on the outside curb side of our TM next to the 12v outlet I installed so we could watch tv outdoors or listen to a distant NPR station by hooking the amplified antenna to our fm radio.
  I went to the back of the antenna outlet box and found two male coax connectors. One of these is amplified and one is not. I used the tv to determine which one was the amplified connector, hooked up a short length of coax cable and ran it through the floor next to the incoming coax. It hangs down about 5" under the trailer. I used female connections on both ends and then screwed in a male splicer on the outside end which allows me to plug in the cable to the tv or radio.
  For the radio, which we use much more than the tv, I use a 75 to 300 ohm adapter with a splitter for the fm signal and a short length of 300 ohm lead in wire on the fm output with 2 alligator clips on the other end. By attaching the alligator clips to the antenna on the radio we get much improved fm reception.  
  I think (but am not sure) you could run your satellite or cable in the same way by using the non amplified connection on the back of the box.
