Without the toroid and secondary, ALL of the power put in directly turns to heat in the primary caps and
coil - not a good idea unless you just want a short-lived space heater with blown caps.
I don't know of anyone building a stack as you described.
Unless you want to see a lot of FCC trucks in your neighborhood, I don't think you want your coil to be a
good RF radiator.

Subject: [TCML] Couple questions on coiling
On strike rings can you have more than one as long as they dont make a full
circle? Will a sheet of lexan over primary help insulate it or can a strike go
through the sheet of plastic?
As far as running the coil can it be ran without the toroid and without the
secondary? I'm thinking not since its tuned all together, curious if anyones
done it?
Has there ever been a coil built with 3 primary coils ie a large one on bottom
not connected to anything the normal in middle in circuit and a smaller one on
top. Like a vertical yagi with driver element reflector? If there's any hams
in this group they will know I mean I hope.
