My next project is a Berliner Joyce OJ-2 scout, both land and sea versions. Paul Matts drawings show what is called a Harp Antenna strung between the wings two places on one side of the plane. See the picture below. Easy to see why it's called a Harp Antenna, it looks like two sets of harp strings. I cannot find out how this was used as my Google efforts all point to an arrray used in the Artic during the cold war. Does anyone have a reference to this thing? Inquiring minds want to know.
