Jim AB9CN sent us Dan Zimmerman N3OX’s page in response to my plea for help in SolderSmoke #227. I think this is a very clever and attractive way to cover both bands with a single Moxon.

Of course there are other ways to do this — other listeners wrote in with confirmation that it is indeed possible to nest a 17 meter element inside a 20 meter Moxon (as is done routinely with Hex beams), but this requires a lot of cut-and-try tuning of both antennas. More in this in future posts. Thanks Jim, and thanks to all who wrote in.
I kind of like the N3OX approach. I think his design makes it more of a workbench electronic project, as opposed to a mere wire and coax antenna project. But hey, that’s just me.
