[Milsurplus] RE: Aircraft HF DF capabilities New Question

[B. Smith]

     Yes, I am aware of several receivers that were used in WWII that had HF 
capabilities and several had  a "loop" input that may or may not have been 
disconnected when the receiver was tuned to a "HF" frequency.   Actually any 
receiver can be used for DF'ing as long as it has some sort of gain control 
and the operator has the skills to detect an aural null and the navigator 
has the skills to solve the 180 degree ambiguity problem.


      Now I guess my question to the group is:  Does anyone have any 
documentation of a DF antenna that was installed in any military or civilian 
aircraft that  had published design specifications  that the DF antenna was 
to be used on any segment of the  HF band 2.0 Mcs to 18 Mcs. Not special ops 
but normal line mission aircraft.
