Default Homebrew Coil Form Factor

Lovely work Mike -- a bit more than I require but I'll keep it
in mind. Thanks!

Thanks John,


I do require the structure be relatively strong or I
would wind the coil, put epoxy glue strips along it
to make it like AirDux and the like.


Cheers and 73,

Here's a picture of a coil I built years ago using 40 ft Radio Shack
Aluminum Ground wire. It comes coiled at about 8". My coil is about 8" x
8". I'm making an educated guess that it's about 150uh.

I drilled spaced holes in 1/2" pvc pipe and then split it on a band saw
and clamped the wire between the pieces. Need more strength add more pvc
clamps. There are other ways.

I just went to the radio shack website looking for the ground wire, I
have one and it's catalog number 15-035, BUT, I can't find it on their
site.
Hmm, I see one on Ebay, $14.99 including shipping
