The article suggests that 24 270 ohm 2W carbon film resistors, wired into
four lines of six resistors in series, and then paralleled would produce
a final resistance value of 405 ohms, and would allow 300 watts on SSB.

Hope this adds to the discussion.

Hmmmm ...

Any suggestions for a method for dumping the heat from the resistors
back into the shack in the wintertime? :-)

And heck, during the winter, wouldn't it be nice to have the resistors
overall rating able to dissipate a KW and provide more heat?

Since the amount of heat dissipated in the resistors will only be 30-40
watts when running 300 watts SSB output, and since they're halfway up the
antenna, I doubt very much that you'd get much heat output.

It's easy to up the wattage rating, but it costs $ to get high wattage
non-inductive resistors.
