December 1990 QST page 59 has the information for putting the 204BA on
18 mhz. It uses only 21 feet of the boom. That same information is now
included in the newer 204BA assembly manuals. I sent that information
to David VK3EW direct. If someone else needs it, feel free to contact
me. Also, I also have 20 meter operation optimizing info for maximizing
either forward gain, front to back or bandwidth.

You might contact Neil, K6SMF about this if you don't find an article
He runs a converted 204BA on 17 meters and it works exceptionally well.
He used the whole boom length and changed all the element lengths and
spacings per, I believe, the formulas in the W2PV Yagi Antenna book.
