Marshall, your very informative information makes the cage-monopole an even more interesting antenna than I first believed.
My view is (was) simplistic, seeing 4-common 10-foot antennas combined at the bottom. But with your input, it becomes obvious there can be more to it than that.
I’m going to seek links with the details you speak of, so the part 15 community can be equipped with road maps for getting the most out of cage monopoles.
If anyone else finds links, please post them here for our benefit.
