[Milsurplus] [ARC5] DAG HFDF Sense Antenna.

[Michael Hanz]

I can't answer the ambiguity question as posed, Mike, but the need for a 
sense antenna is well documented back in the early 1930s, perhaps even 
earlier.  That and other considerations are described at 
https://aafradio.org/docs/1936_NRL_Aircraft_Radio_Training_Manual_DF_Chapter.pdf 
(page 107 begins the sense antenna discussion).
