C band WR 229 LNB's TVRO +/-2.0MHz

Our C band lnb’s offer top quality digital performance. They cover the 3.7-4.2GHz bandwidth and are supplied in two noise figures 15K (Model AC15) and 17K (Model AC17) Suitable for connection to any Prime focus or offset C band feedhorn.

Corotor II Plus Wideband is designed for systems which require reception of both C and Ku-Band signals. The Corotor II Plus Wideband is used throughout Europe, the Middle East and North Africa, and South America. The feedhorn feature 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 Wideband is for receptions of circular and linear C-Band signals in the 3.4-4.2GHz range and linear Ku-Band signals in the 10.95-12.75GHz range. The Corotor II Plus Wideband features a new low loss dielectric plate. The new dielectric plate provides a lower noise temperature and improved cross polarization.

The Corotor II Plus Wideband 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 Wideband is the ideal choice for systems which require reliable performance.

The Corotor II Plus is designed for systems which require reception of both C and Ku-Band signals.

The Chaparral Super Feed is a single polarity C-Band feedhorn for reception of linear polarized signals in the 3.7 to 4.2 GHz bandwidth. Superior quality, excellent illumination patterns and a compact design make the Super Feed the ideal choice in feedhorns for single polarity systems.

Chaparral's Super Feed features chip-resistant powder paint and cast aluminum construction for added protection against the environment. Built in the Chaparral tradition of quality, the Super Feed is the ideal choice for reliable performance.

Applications: Single Polarity Satellite Systems

Designed for reception of C-Band signals from 3.4 to 4.2 GHz, the PRI E/A includes Chaparral’s reliable servo motor for skew control. In use for over decades in millions of home satellite systems, cable TV systems, businesses and institutions, the Polarotor I E/A has earned the reputation as the best-performing C-Band feedhorn in the world.

The Chaparral Dual Feed feedhorn is an orthomode transducer for simultaneous reception of horizontal and vertical C-Band polarities. Due to its reliable performance with virtually no signal loss, Chaparral's Dual Feed is the most trusted feedhorn for commercial applications.

The Chaparral Bullseye II feedhorn is used in satellite systems equipped for reception of C-Band (3.7-4.2 GHz) and Ku-Band (11.7-12.75 GHz) satellite signals and is compatible with all LNBs designed for these frequencies. Simultaneous reception of both signal polarities is available for multiple receivers using a single dish. The adjustable scalar ring provides optimum reception and interference rejection with a wide variety of dishes.

The optional golden ring is no longer available, but if you set your Corotor or Polar-rotor feedhorn to an f/D ratio for .32 the performance will be fine.

Chaparral's Ku-Wideband Polarotor Mounting Kit features multiply mounting holes for alignment to most prime focus dishes. It displays a convient alignment arrow to position the Ku-Wideband Polarotor with the polar axis of the dish. The kit includes 4 screws to mount the Ku-Wideband Polarotor to the plate and 4 each 1/4-20 screws and nuts to mount the plate to the satellite dish.

Chaparral's Ku-Wideband Polarotor Mounting Kit features chip-resistant powder paint and cast aluminum construction for added protection against the environment. P/N 62-2301-1
