I forgot to add that MFJ makes a switchable inductor for 43' verticals based
on the design by AD5X?  I think that is the designer.  I communicated with
him and he verified it was his design that was used.  I asked for a copy of
the then unplublished technical manual for that device and MFJ sent it to
me.  I was strongly considering either building my own or purchasing theirs. 
It has remote switching using injected voltage on the coax, making it pretty
easy to impliment.
