I always carry two 25-foot coils of RG Cable.
Using a TV Splitter I can hook up both 25-foot cables to the same CABLE TV connection on the camp ground pedestal and run one to the trailer CABLE TV connections and then throw the other 25-foot RG cable under the trailer.
Then we can move our BEDROOM HDTV out to the patio area sitting on a table or just inside the opened pass through storage bay. Works great for us...
Sometimes kinda neat sitting around the outside firepit and watch some NCIS or football games...
Since RADIO SHACK has become hard to find anymore we find all we need at WALMART and LOWES...
