That would not be very practical, because it would be 100 turns. I
suggest using the existing 30dB design, and add external inline BNC
attenuators like the Mini-Circuits HAT-10. That would give you 40 dB total.

What combination of core/turns would give up to 40dB and able to
handle 100 watts and what frequency range would it have? Main interest
is HF

Hi Michael,
I designed the CP1 for Elecraft and in the process I performed many
tests to evaluate the power handling capabilities. The power is
limited by heating of the core and that is primarily a function of
flux density and time. The published specification allows the rated
power to be applied for long periods of time without excessive heating.
