You can place your driver as great distance away from the resonator if you
use a transmission line.  Two 4 inch wide pieces of flat copper adhered to
a 1/4 inch thick piece of plexiglass works good.  Some experimenters just
use a non-grounded feed -- essentially a 1 inch dia. copper tubing/pipe
(water pipe) also works very good.

Best design is to have the cap and spark gap near or under the sec --- then
maximum energy transfer occurs assuming other design parameters are within
normal spec.
