Neptun (radar)

Neptun. Working in the metre range, Neptun was meant as a stop-gap until scheduled SHF-band devices became available.
Transceiving antennas used for Neptun on twin-engined night fighters usually used a Hirschgeweih eight-dipole array with shorter elements than the previous 90 MHz SN-2 radar had used or as an experimental fitment, the 90°-crossed twin-element set Yagi based Morgenstern single-mast-mounted array.
