Forwarding this post i made, for possible interest to one or two people.

The "teardrop" shaped DF antenna housing on large U.S. WW2 warplanes held a standard round loop antenna. They do seem rather rare for how many were produced. Perhaps it was similar to the situation for avionics mountings and control boxes and such: if it was very easy to remove when the plane was scrapped, it survived; otherwise not. 

The Reich had a very compact RDF receiver, the EZ6, about a 7 inch cube, which only tuned up to about 1 MHz, which upper freq limit i do not understand. It used a ferrite core bar antenna, much more compact than the U.S. "teardrop" or "football" shape. I think this antenna was rotated by servo remote control, but i'm not positive. Similar survival rates to U.S. equipment apparently. I have a photo of a bunch of JU-88 bombers parked in Denmark at war end. I thought, "Please let me ( or someone ) have about an hour, at least, taking out some things, before you crunch up the planes".

I am old enough to remember when the "Lady Be Good" B-24 crash was discovered in Libya. I thought the fatal mistake was largely the ground station's, not making sure the DF bearing was true and not reciprocal. 

A few years ago i bought the same date of LIFE Magazine that carried the story of the search and recovery.

Great photos.
