Did anyone know were I can buy foam or similarly substance?

emersoncuming sells controlled dielectric foam. I've purchased Er=1.12 and Er=1.2 from them before. The higher Er was good to machine and form a 1-40 ghz bicone support out of it. Nice low loss too.

Here's a link for dielectric foam stock, or foam in place powders for Er=1.03 to 1.25
