We used a portable radio with the bar antenna on it, that we rotated
the radio to get the best signals from different San Francisco and
Oakland radio stations to find the Golden Gate Bridge entrance to SF
Bay. We never failed to return home, so was a valid system.



Heathkit used to make an RDF little portable receiver with a loopstick
mounted in a rotating housing on top for RDF fixes. Worked great!
