Ed,
How about a vertical array antenna? It's as omnidirectional
as an antenna can get in a 'real world' situation, and it does
have gain over a single element antenna. Describing it with
the commonly accepted definition of a 'beam' isn't
correct/valid,
(I agree with you there), but it fills the requirements of the
original post (omnidirectional + gain).
'Doc

What do you mean by a "vertical array"? What are the basic radiating
elements, loops or dipoles? And then, how many replications and in what
physical location is this "array"?

Could you be confusing "omnidirectional" with "omniazimuth"? Another poster
visualized this antenna pattern as a squashed (mmmmmmmm) doughnut. Equal
radiation to all points on the horizon, all the way around the compass. But
that pattern isn't omnidirectional. For instance, what about straight
overhead? Is the field as strong there as at the horizon?
