Definitely not feeling the Google love today! Anyone have an idea of the 30MHz power handling capability for RG6A/U and Belden 9104? I have some RG59A/U as well but having seen RG58 melt I'm not incl

RG-numbers are essentially meaningless -- the tell us nothing more than approximate size and Zo. The Belden data sheet https://catalog.belden.com/techdata/EN/9104_techdata.pdf tells us that 9104 is a

Martin, Its really first about expected loss for 30 Mhz - isn't it? Why put 1KW into a cable that has loss of 1.8dB per 100 ft? How long a run are you planning? Ed N1UR -- Message: 1 Date: Sat, 6 Jan

I have run 1KW into RG58 with near 1:1 SWR on 40M/80m. The cable did warm up afew degree's but it never failed. However, on 15M to the same 40m antenna the foam dielectric flowed essentially melting

Thanks for all the inputs, much appreciated. Maximum run length for the 75 ohm cable would be 1/4 wavelength on 28MHz. For other bands just a couple of feet as a series section transformer in each ca
