You dont have too many choices between ceramic and hard Teflon if high power
is run. Look around for large surplus chokes such as maybe from a scrapped
BC or WW2 military TX that are often pi wound. Strip the wire and start
over.
Ive also seen hollow ceramic forms used for RF coils that may be a good
candidate.

Subject: [Amps] Rf choke coil form
I need a recommendation for a material to use in a coil form for an RF
choke. The existing choke is about 1.5" diameter by 4" long. I would
like to use ceramic but I can't find anything in this size, also what I
have found is really expensive. Recommendations?
