Wal~Mart carries the rubber self-fusing tape.Great stuff! It's in the plumbing section.Keep in mind,it is NOT,UV protected,so you will need to cover it with some good 3M electrical tape.I use the appropriate size heat shrink tubing.The stuff is all over eBay,and,pretty inexpensive.I think I gave about $4.00 for a 6ft roll that will fit a Type 'N',or, PL-259/SO-239 connector.
