I see you are using a tuner. What was the SWR after the tuner. Having 1:1
into the tuner does not count. 9913 should easily handle 10 KW. I can run 2.5 KW into a dummy load thru RG58 (perfect match). A problem with 9913 is that if it flexes or is bent often the center conductor will wallow out a large space in the foam insulation and get way off center. Good old RG8 is best for HF and flexing feed line. 73 Bill wa4lav At 03:51 PM 2/9/2004 -0500, kce wrote: This past weekend I was loading up a amp into a OCF dipole fed through a 4:1 balun with 9913 belden cable. When I hit the 800 watt mark a big spark, so I figure ok the 4:1 went west on me. I change out the balun try again same results. I change out the feedline to rg/213 no problem. I check over the 9913 and find a fair sized arc hole in the cable about 15 feet below the antenna. Anybody else have problems with this cable. There are no signs of moisture present in the cable, God knows I spent 1.5 hours looking for it. I see on the belden site they claim 10 KW rating at 1 mhz for a 1:1 vswr. No damage to the amp or tuner.
