I always carry a short type F cable, a splitter, and two 25-foot type F cables.
This allows me to connect the short top connector to the TV source on the camp ground pedestal, then connect one of the 25-foot cables to the CABLE INPUT connector on the trailer, and the other 25-foot cable to lay under the trailer and be available to plug into a portable TV sitting on a small table under the awning when we want to sit outside and watch some TV.
I always always have a couple of barrels type F barrels in the tool box to make a 50-foot cable out of the two 25-foot cables if needed.
Always have PLAN Bs...
