Doug, If your antenna is going to be subject to 100+ mph winds, it should be braced at the top, and possibly in the middle as well. Moreover, there's no way that any antenna that is supported only at the bottom will survive extended exposure to high winds and ice buildup. The answer may be to side-mount the antenna on a standoff, with an insulated top brace. If the antenna is constrained from waving in the wind, even a medium-duty antenna will stand up well to blustery winter weather.

Thanks for all the recommendations. Fired an email off to Scala, curious to see what they come back with. I read thru a few Scala datasheets... curious that they do not give wind loading with radial ice... and... just my .02 here... from the pictures in their catalog... those antennas sure don't look very durable to me... keep the recommendations coming - specific models would be quite helpful (especially at 440MHz) doug
