Typed caption on verso: "H. Shows an early attempt to tune the loop antenna at the antenna, itself, to eliminate the losses attendant to a long loop line. Also you will note that there were two loops in the fore and aft plan, one for the broadcast band, and one for the beacon or 200-400 KC band. There were also two loops in the A beam plan which were considered for the purpose of eliminating the vertical antenna requirement as it was thought if the ?vertical? [sic] antenna problem could be eliminated, the problems of precipitation static could be eliminated."Creation Datecirca 1931-1939SubjectLear DevelopmentsLearadioRadio in aeronauticsAntennas (Electronics)Aids to air navigationExtent1 photograph : black and white ; 8 x 10 inOriginal Formatphotographic printscomposite photographsBibliographic CitationThe William P. and Moya Olsen Lear Papers/The Museum of FlightRightsCopyright undetermined
