I didn't think that the frequency could be suppressed as mentioned in your
last sentence.  I am not sure I can agree with the statement that aluminum is
a poor conductor at TC  frequencies.  Chip uses a primary made from a strip of
aluminum(about two inches wide) cut from a roll of flashing.  His coil does
quite nicely with it.  Perhaps it would do even better with a copper strip of
identical size, but as far as I can tell, aluminum works just fine.  Maybe
this is simply due to the large surface area of the conductor.  Whatever the
case, I wouldn't hesitate to use a similar design.
