Hi LF, Mike, Tom!
Will be helpful for anybody, but on russian language:
Old discussion at 136.su russian LF forum about ferrite ants and DM4TR grabber
with ferrite ant practical results:
http://136.su/index.php/topic,119.0.html
The other old discusion on radioscanner.ru forum:
http://www.radioscanner.ru/forum/topic22993.html
-Many practical results from different OM's into forum but on HF band mainly.
Russian book - main hand-book of all ferrite antenna designers in Russia:
Khomich V.I. - The receivig ferrite rod antennas, but on russian language only.
http://www.radioscanner.ru/files/antennas/file1138/
The wide-band ferrite rod original practic construction - OLUSHA-T from Sergey
Zadorozhny from Kiev:
