I carry two 25-foot RG cables. I also carry a very short section of RG cable along with a 2-port splitter. If I don't have use the second long RG cable I hook the short RG cable to the cable TV port on the pedestal and the other end to the two port spliter. The connect the two long cables on the two output ports of the splitter. One goes to the cable TV port on the trailer and the other long cable gets throwed under the trailer.
Now we can use the RG cable under the trailer to run our TV setup from the patio area if we want to watch some TV under the stars...
