Re: [AMRadio] RG-6 Coax
Carl, the rated voltage of all Belden RG 6 cable is just 300 volts. The one I copied from the Belden site used PE insulation. They have other types of insulation and there is also a difference in burial and Plenum cables as far as some stats. go. I am saying, be careful what you buy, for manufacturing tolerances may be different than what the spec says, evidence the toy recalls and pet food fiasco. The voltage of 600 watts is about 205 volts, just 95 below the maximum rating of RG 6. Again, provided the match is good so you don't have heat build up on the cable, it is ok for the good quality cable. Buyer beware. I have some RG 213 made by Alpha, I think, that I would avoid buying every again. Although a name brand, it suffers from poor quality control and manufacturing tolerance. When I try to strip the inner insulation, the center conductor and inner insulation tries to come out of the shield. I have pulled as much as 6-8 inches of the inner conductor out. Jim/W5JO H, since all RG-6 uses a foam dielectric your comment is rather confusing. The premade Chinese cables available at box stores and raw unbranded cable should be suspect of course. I use Com Scope and Times as they are readily available from CATV crews in useable lengths. Also consider that there is a substantial margin to the published breakdown voltage and youre good to go at a substantial power level. Ive known hams that use RG-58 to feed HV to amps at over 2500V! Many years ago I used RG-6 as the coax part of a G5RV at 600W and never had a breakdown even at the rather high VSWR. The power levels Ive mentioned are for CW and SSB, derate for AM.

A very incorrect statement. CATV foil is bonded to the foam dielectric, it doesnt "crinkle" as with audiophool stuff. The better CATV cables are Quad shielded.

Rick, I've been bit with 5KV and 15KV. I spent some time working power distribution. Both times ALL precautions WERE taken. The stuff can become unpredictable! Bob Rick Brashear wrote: Oh buddy..
