[TowerTalk] Where to get LMR 400

Yes, the current heats up the dielectric around the center conductor.
RG393 with the same conductor size and its PTFE dielectric is specified at
9500W on 6m.

MIL-C-17/74 (RG 213 spec) sort of says that..

It says 3700V rms maximum

Figure 2 shows the "straightline" from 1200W (@50 MHz) down to 180 W 
(@1000 MHz), probably based on thermal limits from the current in the 
center conductor - 0.0888" OD seven strands that are 0.0296" each 
(between AWG 20 and AWG 21)
