GA aircraft still have this wire. This is provides the Automatic Direction Finder (ADF) with a "sense" signal. To wit: A modern ADF requires several antennas; a "loop" antenna for direction finding, and one "sense" antenna to resolve 180 degree phasing ambiguity. On GA aircraft (and older, non-transonic transports), the sense antenna is often a long wire stretched from the tail to the forward part of the fuselage. ed -------- Ed Hahn | firstname.lastname@example.org | (703) 883-5988 -------- The above comment reflects the opinions of the author, and does not constitute endorsement or implied warranty by the MITRE Corporation.
