How did we get from solid spacers to rope? http://www.sdplastics.com/ultravioletresistance.html

Wes N7Ws>> None of that may matter because the electric field strength in the insulator is probably low and almost all nylon has UV inhibitors now. The rope I use for antennas is nylon and it lasts a very long time in the Georgia sun. You have to look at the material characteristics of the particular nylon material for UV life, and the end application for dissipation factor problems. Even 100 times nothing might still be considered nothing. 73 Tom ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
