Corotor® II Plus
Dual Band Feedhorn
|
Description
Chaparral Communications has increased performance and value
in the best-selling dual-band feedhorn with the Corotor II
Plus. It features Chaparral's patented probe design for
C-band reception and a unique low-loss dipole antenna for
Ku-band reception. The dipole is virtually invisible to the
C-band probe, resulting in superior C-band performance while
improving the Ku-band illumination. Both the probe and
dipole are controlled by the Chaparral servo motor,
providing infinite skew adjustment and quick selection of
horizontal and vertical rejection with the widest variety of
dishes, from .45 to .30 f/D.

Applications
The Corotor II Plus feedhorn is used in many home and
commercial satellite systems for reception of C-band signals
used for broadcast of entertainment television, and for
reception of Ku-band signals used for network, business,
entertainment and educational television.
The Corotor II Plus features an adjustable scalar ring to
tailor the feedhorn illumination pattern to the curvate of
the dish for macimum signal and minimum noise. The
adjustable scalar ring can also help reduce the affects of
terrestrial microwave interference (TI) on C-band satellite
signals by underilluminating the dish. A simple-to-use f/D
gauge is cast into the side of the waveguide for setting the
scalar ring with a unique single adjustment set-screw.
