Bill Orr's handbook, 16th edition, p. 418, saith:
RG-8/U will handle 2kw at 30 mHz if swr is low
RG-11 will handle 1.4 kw """"""
RG-17U will handle 7.8 kw """""
RG 58/U will handle 430 w """"
The 22nd edition, p. 25.15, saith:
RG-8A-/U 1720 w at 30 mhZ
RG 213/U 1720 w
RG 58 580w
RG 11A/U 1,400 w.
p. 25.17 saith:
CABLE POWER RATING: The factor controlling the power capability of a
coalial line is heat, most of which is generated in the center conductor.
The inner dielectric's ability to withstand the heat and its effectivenuess
in transferring heat to the outer shield and jacket are the limiting agents
in the heating process. For vhf/uhf use, coax with a teflon inner
dielectric are used, which permits a center conductor operating temperate as
high as 250 C.
