Hi Jim,

As Richard pointed out, a goniometer (what, a 100 years old already?)
works fine for this. I bought one at a Ham swap when I was a
teenager. I also pointed this goniometer/antenna application out to
Arthur to demonstrate what he thought was novel was quite old (in
reference to the work of Tosi and Bellini). Arthur does not
acknowledge prior inventors, so this topic consistently re-emerges
with a fair periodicity. It should reappear around July again.

For those who want to see a schematic of the goniometer and antenna
application, here is a perfectly good example:
