The Corotor II Plus is designed for systems which 
require reception of both C and Ku-Band signals. The 
Corotor II Plus is primarily for reception of 
satellites in the United States and features 
Chaparral’s patented probe 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 Ku-Band illumination. Both the probe and the 
dipole are controlled by a Chaparral servo motor, 
providing infinite skew adjustments and quick 
selection of horizontal and vertical poles.



The Corotor II Plus receives linear C-Band signals in 
the 3.7-4.2GHz range and linear Ku-Band signals in the 
11.7-12.7GHz range.  The Corotor II Plus features 
chip-resistant powder paint, waterproof gaskets and 
connectors for protection against the environment. 
Built in the Chaparral tradition of quality, the 
Corotor II Plus is the ideal choice for systems which 
require reliable performance.
