Hello everybody,

I have a couple questions.  Would you wind 1800 turns for a 1/2 wave
bipolar (based on ~ 900 for a 1/4 wave TC) for the secondary or is there
some other optimum number of turns?  Also, what is the H/D ratio that is
most commonly used for bipolars?  I'm interested in building a small
bipolar with a secondary length of about 20" for demonstration purposes and
ease of portability.  If someone out there has construction info or ideas
on this I would be greatful.

							Thanks, Mike Hoffman
