Clever arrangement for the dual pivots.  Thanks!

HAVE YOU EVER BUILT AND HF ADCOCK ANTENA? THEY SAY THEY ARE WAY MORE ACCURATE. LIKE TO SEE VIDEO ON THAT MAN.

It's pretty difficult to match the null (and the direction/bearing it indicates) that is produced when a loop like this is 'flat' to the signal source; that being said, an Adcock loop used in a more sophisticated DF receiver would offer benefits like being quicker to use and nearly automatic in operation unlike the loop used here.

An Adcock-based system would still show some difficulties (poor bearing) with a signal showing a high incident/incoming angle like shown here ...
