Jim,
I purchased them many, many years ago when they were relatively
inexpensive. Thank you for enlightening me as to their content and quality.

Hi Carol,
Amidon does not make cores, they sell stuff made by other companies,
and terribly high markups. 2.4-in cores are made from dozens of
different magnetic materials, all very different from each other.

Hello,
At present I have an inverted "L", 100+ feet vertical with 4 elevated
radials, about 130 feet long at 10 feet in height. I am about to
construct a CM choke. On hand, I have 4, Amidon 2.4 inch cores. From
the reading, it seems that I should have 5 cores and about 5 turns of
RG8 coax. I can I get away with 4 cores?
