Also I understand that coax power handling capabilities should be de-rated
as the SWR goes up.
Any one have a formula for this ?

Does anyone have experience with how much power can be run through rg-58
versus rg-8. I am purchasing an Ameritron al-80B and will be running
about 1K out. Can I still get away with RG-58? I will be using 160 thru
40 meters. I have a 200 foot run of RG-8 running to my antenna site, but
I hate to feed the dipole with something so heavy as RG-8.
thanks in advance for any help

At 10 MHz, the power rating for RG-58 (Polyethylene Dielectric) is 730w
and for RG-8 it is 3700w). For foam dielectric, use something like 50% of
the above. Note that RG-8x is rated at 1000w at this frequency.
