Tom,
If you get the chance could you try a coil that is tapered?
I envision something along the lines of wrapping coax around those orange
cones that are used at roadwork sites.
There is a company (whose name escapes me at the moment), that is making
tapered RF coils that operate over an extremely wide frequency range
although these are filled with ferrite.
Just a thought.
