In 2007 (15 years ago) I ordered 100 feet of Times Microwave Systems LMR400 Coax. It has since sat, unused and still in the shipped coil, in my garage. The garage is protected but still subject to south Florida heat and humidity. I want to use this cable now for a VHF/UHF dual band antenna in my attic but would first like to get an idea if I could expect to have degraded over those 15 years.
