For a BCB antenna, 1/2 wave (for 900 kilohertz, the middle of the range) woulds be 333 meters / 2, or about 167 meters, even 1/4 wave would be about 84 meters, both pretty long. If the antenna was a "simple dipole" I would like to know what the length of each side was, because that would tell what the antenna was actually tuned to. To tune it for BCB, but keep it to a reasonable size, I would imagine a loading coil for each leg was probably used.
