I got this from this morning’s Amateur Radio Weekly newsletter. This looks like an interesting antenna to try on some POTA activation.
After watching the above video, I got to thinking about other directional antennas that I could possibly use for portable operation. Moxon antennas, in particular, would seem well-suited to this task because they are smaller than Yagis. Searching YouTube yielded this video on building a 15-meter Moxon.

And, finally, here’s a video on how phased arrays work to begin with.
