     I would expect minimal change.  The body (conducting part) 
     changes in diameter relatively little.  Like hardly at all.
     The Oxide is low loss (i think?)

     I guess.  But there 10 MHzish (cuited in one article)
     is a bit different (2 to 3 orders of magnitude) that typical
     Tesla freqs.
