Re: [TowerTalk] DIY Air Wound Coils

[Rob Atkinson <ranchorobbo@gmail.com>]

QST had an article a month or two ago about using a 3D printer to make
coil forms.  Not a word anywhere in the article on the carbon content
in the material, or if it's lossy at RF.  First things that went
through my mind, especially since the material was black plastic.  I'd
put the coil form in a microwave and see if it heats up and see if it
has any less-than-infinite resistance.
