Just a note that I've moved my coil inductance and Q calculator to a new
home. You'll find it at the bottom of this page:

Check the version number in the link. If it's new, click to download.
COIL 3.22 has a number of improvements. It features an automatic Q
optimizer, handles coils made of Litz wire, provides an RLC model useful
for broadband antenna analysis, lets you explore coil properties with
the mouse wheel, and is even more accurate. See COILS.TXT for updated
accuracy validation figures. See READ.ME to overcome some Windows quirks.

P.S. - A guy made a nifty antenna loading coil form using his 3D
printer. I added PETG to the list of form materials so the program could
model the loss. (It's fairly lossy, similar to nylon at HF.)
