[TowerTalk] step ir vs zero five

[Barrie Smith]

This chat about Zero Five verticals got me curious, so I went to their site.

I discovered a 57' vertical that "looks" good, so I called the number.  The 
website says he's open on Saturday, but no luck.

I'm wondering if anyone on the list has this 57' vertical in use and what 
your experience is.

I'm especially interested in whether it must be guyed.
