What is the function of a sense antenna?
Pick an answer to check it.
Answer: A. It modifies the pattern of a DF antenna to provide a null in only one direction
A sense antenna adds to a loop or DF antenna's pattern so there is only one null. That removes the 180 degree ambiguity.
Tip: Sense antenna: one null, no ambiguity.
