Chris,

Discones are cool skyhooks....and very broadband, but not much gain.   Have
a look at  The ARRL Antenna Handbook the chapter on broadband antennas --
Discones.  Also, the Antenna Compendium # 5 has an article.  Or if you feel
historic, see CQ magazine July 1949....a first look at the Discone for ham
work.    A discone is simply a coaxial transmission line that has been open
and splayed or fanned out.  Shield bent over and center wire to the disc.
