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.
