Here is a quick tip for those of you that have been on a camping trip and watching TV, only to have the cable connection on your RV short out due to rain. Wrapping the cable with electrical tape can be a hassel. You will always have to retape it every time you go out. Here is your solution, by using a spark plug boot, which can easily be slid on and off the connection. It makes a tight and dry cover for cable or satellite hook ups.
