Wow, Thanks to Ed, KB5GT for this power and loss calculator for any type of coax. http://www.timesmicrowave.com/calculator/?productId=118&frequency=2&runLength=400&mode=calculate#form

Amazing, RG6 can take 2 KW on 160 meters!

I repeat my advice from yesterday -- WHICH RG6?

RG-designations used to be rigid specifications for cable. That has not been true for at least 40 years. All the RG-numbers tell us is the impedance and the approximate size. RG6 cables are somewhere between RG59 and RG11. If you believe it tells you more than that, you're out of touch with reality.
