Conical scanners are configured with upward-firing feedhorns in which the reflector redirects the FOV back down toward earth.

Millimeter-wave satellite remote sensing

A feedhorn has been developed that mates with the LNC's circular waveguide and operates over the entire 11.7 to 12.7-GHz Ku-band allocations.

For example, in a reflector antenna, the bend system can enable the orthomode transducer or polarizer to be located away from the feedhorn. This configuration is an advantage in certain antenna systems.
