I had VSWR developed flashover when using RG6 at 1200W. The 80M dipole was
cut for CW and it just didnt like operating up at 3.9. I used CATV quad
shield with F connectors and the arcing wasnt at that point. It blew the
sides of the cable out about 20' down!
I then went with CATV RG-11 and in over 25 years Ive never had problems with
that style cable or F connectors; invested in a commercial crimper with 3
dies. My complete station from 1.8 to 432 is 75 Ohms; lots of hardline up to
1". I use the RG6 for Beverages.
