John, I have several of these up for repeaters here on the Oregon Coast. They hold up pretty well. I would recommend a top brace if they are in a harsh environment. I like their performance on UHF, they work very well for their size and price.
On VHF they of course are a little lacking, and I have found they compare to the performance of one of the single Telewave broadband loops. We have one on a 4000' mountaintop that sees a fair amount of snow and ice and it has survived 2 winters up there so far. Hope this helps, Joe - WA7JAW --- In Repeater-Builder@yahoogroups.com, "John Mackey" <[EMAIL PROTECTED]> wrote: > > Anyone have any opinions on the Diamond X-50NA?
