[ARDF] HB9CV dimensions? in PVC?

[Matthew Robbins]

Does anyone have the dimensions (or a link) for a 2m HB9CV antenna? 
I've been looking, but most of the links are for HF antennas.  I've
also found a link with the phasing section of the Czech Compact 144,
but it doesn't have the complete element lengths:

I'm thinking of making one with an H-shaped frame of PVC pipe holding
the phasing lines, with tape measure material extending past the
phasing line attachment points.  (Does that description make sense?)

Are there any trimmer components in these antennas?  I've seen some
references that mention them, but no information past that.  Are there
any technical descriptions of this antenna?  (Maybe I should check the
ARRL antenna handbook...hmmmm.)

I'm trying to make a small, light antenna for kids.  (And if it works,
maybe for me, too.)
