There are many errors in this post, which I have neither the time nor the energy to correct.

I refer the author to the many tutorials on my website, k9yc.com All of which has had considerable peer review, and much of which has been part of the ARRL Handbook and Antenna Book.

Losses present themselves as heat.

Yes, they do.

But doing so moves the self-resonant frequency of the chokes, and the effectiveness of chokes depends on this resonance! I strongly suggest that you study my work on this, first published in 2005, expanced and updated many times over the years.
