It's not THAT the wind blows, it's WHAT the wind blows.  It doesn't matter 
how many push ups you did that morning if the wind throws a Volvo at you.

 I helped design a network that worked through a hurricane out on the
 barrier islands near NC.  We did NOT use adhoc but rather put in ptp or
 ptmp stations.  It was pretty amazing to see video feeds from inside the
 hurricane.  Cool stuff.

 We used mainly Zcomax gear at the time.  Just off the shelf stuff.

 Let me know if I can be of help.  Maybe I can get lucky and find the guy
 that actually built if for you.

 Very cool, I will pass on that info, as well as the info of those who
 wrote me privately.

 The project (to my knowledge) isn't a go yet, it's just a pain point
 that I know that they eventually have to address.

 Right now, he's generally looking for vendors that are willing to put in
 writing some of their ruggedness claims or have had experience putting
 up installations in tough environments.  For example, BelAir Networks
 says (something like) the following in their claims:

 BelAir nodes and mounting systems are designed to operate and survive
 in windy conditions of up to 165mph gust, 100mph sustained.

 While those claims may look okay, and their brackets look okay, I'm
 wondering if the antennas could take the same abuse.  Is there
 hurricane resistant antennas?

 Thanks for the feedback!  This info is great!

That's actually a good point.

So, if you're going to protect gear in a hurricane, it becomes important 
to put the gear in some sort of other protective enclosure.

While just about any radio could be protected, what do you do about 
antennas?  They (particular omnis) must stick out and be exposed in 
order to work properly.
