[RFI] Old wives tail, or true?

[Jim Brown]

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.

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.
