“Cheese-Antennas”

Cheese antennas are very flat, single-curved parabolic antennas bounded by flat metal sheets. They have the appearance of half a cheese loaf and thus received their nickname. Due to the very flat design, they have a rather large vertical beamwidth. In the past, they were used on smaller ships to compensate for heeling with this large vertical beamwidth.

Double cheese antennas used two of these antennas on top of each other.
