As I mentioned in my post, the antennas listed are what I would LIKE to
put up. They are not up on the 48' HDBX as I know it won't support it.
No warning required.
The tower currently has an Cushcraft A3S with a 40m add-on, a 3 element
6m beam, and a 2m/440 vertical. It has thus far withstood multiple 85+
mph wind storms without issue.
I am looking for a more robust tower, still in the 48' range, that can
use the same mounting as the HDBX tower. Is there such a thing?
