You might take a look at "Baluns: What They Do and How They Do It". It
was published in the ARRL Antenna Compendium, Vol. 1 and is now
available as http://eznec.com/Amateur/Articles/Baluns.pdf.

I just finished looking at the new ARRL handbook's section on Baluns. I was
astonished at how little I understood. The "bazooka" balun described in the
book looks like something that does nothing. Anyone know what I don't
understand?

Anyway, what's wrong with a simple transformer - primary attached to
unbalanced coax line from transmitter, and (grounded) center tapped
secondary attached to balanced dipole?

In fact, do I really need a grounded center tap?
