    I have numerous rolls of of RG8, RG8x and RG6 , I went to Pasternex ? and studied the notes on the COAX and none were over 100W and the RG8 was 180W , I am guessing that this refers to the 1GHZ Freq. how does the 1 GHZ copare to HF Freq?. I am rewiring my shack and am using RG8x from the radio to SWR/WATT M to WAVENODE 2n to Wavenode sensor 1 to the SB220 Amp input and LM400 to sensor 2 then to the Antenna. The large 400 was to difficult to get bent in a myriad of shapes to wiggle around. Does this seem to be doable

    Any of those cables should be good for 1KW on HF, assuming low SWR.

    I run 500 watts routinely using DXE RG-8x, and have run 1 KW intermittently, all 54 MHz., and lower. I use RG-8x for all internal jumpers, and LMR-400 for all runs longer than 40 or so feet. I would not worry about anything but loss using RG-8 for any run up to a KW below 28 MHz.

    No problem using it on HF with low SWR/ you can run full power on SSB.
    I use a lot of good RG6 (1000s of feet)

    Me too, except where you use LMR-400 I use DXE RG-213.

    I melted rg8x at about 1050 watts. It is rated for 900 I found out later. The entire length turned to goo.
