Hi Bill - great to hear another station soon on 222!  I use a 
homebrew version of the K1FO design that I built from the handbook 
(not the antenna handbook).  It is a 16 ele design that is really 
great.. one of my favorite antennas.  Boom is more like 17 feet but 
very low wind load, nice gain, and (according to the text has a clean 
pattern).  Mine has a home brew T match made from RG402, #12 Gua 
copper wire and a couple of chunks of aluminum ground bus with holes 
drilled for the tuning rods.  I'm sure that directive systems among 
others offer a similar setup.  I know M2 makes a 5WL (longer boom I 
think) and C3I has almost the indentical unit to mine available at:  
(http://www.c3iusa.com/data/fo16-222.html)
My antenna has worked great from the moment I put it on the air  - 
even worked several hundred miles QRP from here.   Good luck with 
your setup ... my 2 cents - for 17 feet long the 'FO 16 is great.
73,
