[Roger A. Cox WB0DGF]

Danny,

I would recommend an open-sleeve driven element and interlaced parasitics
as shown in the diagram below:

__________________________  17R

          _________________  12R

          _________________ 12sleeve
  ________________________ 17DE
          _________________ 12sleeve

           ________________ 12D1

    _______________________ 17D1

            ________________ 12D2

If you have AO, this should allow you to optimize for each band.  For more
information on open-sleeves, see the multiband section of the ARRL Antenna
handbook.
