Thanks, Mike. I didn't start with a lot of details as it's a little OT for
this list. That said, there are lots of communications folk on the list and
I knew I'd get some good answers. Specifically I'm looking in the 15 to 30
square foot range, @ 100-120 mph. We get a lot of wind.

Topically, I do use a lot of Linux to make my towers useful. :)

Good advice. I have several free-standing towers, as well as guyed towers,
pop-up masts, and the ol' roof pole here and there. I'm losing space on a
colo tower (telco is out of copper, so to speak) and needing to add another
myself.

Sabre does have at least two lines that would work for this particular
task, as does Titan. I have found a better match with Sabre.

For vendors, it's always possible Frigid North has something, but I believe

I can check on this, but Frigid North only has lighter towers in stock, I
believe.

Thanks for the leads. I will check them out.
