Original poster: Yurtle Turtle <yurtle_t-at-yahoo-dot-com> I have a roll of F11TSEF coaxial cable. A spec sheet can be seen at: http://12.150.137.214/CommScope/Eng/specsheets2.nsf/0/DAB619FBF98AC8D285256763007113B1/$FILE/F11TSEF.pdf?openElement Does anyone know if this is any good for HV? The dielectric is gas expanded PE, which I gather isn't so hot for HV. thanks Adam
