A high gain omnidirectional antenna?

[jdalton at bigfoot.com.au]

I was just reading the wireless page at
http://www.air.net.au

It refers to "a high gain 2.4GHz omnidirectional antenna".
Isn't this an oxymoron?  How can an omnidirectional
antenna have high gain??  I presume what is really
meant is a "low loss omnidirectional antenna"?

It's a small point, but it does impact on the credibility of the page.
