Field Proven Performance, Reliability and User Friendly Operation
All central receive systems are not created equal. For more than 38 years broadcasters have relied on NSI Quad™, Superquad™ and Silhouette™ central receive antenna systems for analog and digital applications.
Compatible with single-input receivers as well as diversity receivers, the Superquad™ and Silhouette™ represent the state-of-the-art in central receive antennas. They provide critical performance advantages required to maximize the area of coverage and to ensure robust digital live shots. In addition, they are built to ensure years of reliable operation with minimum maintenance.
Advanced Antenna Design
The Superquad™ and Silhouette™ incorporate important characteristics that are essential for superior performance - high gain, directivity and selectable polarization - to isolate the microwave link from interface and to provide the maximum area of coverage.
Variable Gain LNA/BDC with AGC
The dynamic range of the LNA and block downconverter (BDC) has proven to be a critical determinant in maximizing the area of coverage for digital shots. Modern LNA/BDC designs have little difficulty handling low signal levels, as found in a distant shot. However, a high signal level from a transmitter close to the central receive site can saturate the LNA and/or overload the receiver, which will cause a digital shot to fail. Superquad™ and Silhouette™ central receive antennas feature a unique LNA/BDC assembly with a continuously variable level control to ensure the robustness of live shots from practically underneath the antenna out to the radio horizon and everywhere in between. The
Automatic Gain Control function of the NSI
MC5 remote control automatically optimizes the LNA/BDC level to maximize the RSL without overloading the receiver.
Superior Reliability
One of the hallmarks of an NSI product is the way it is built. The Superquad™ and Silhouette™ are designed to ensure years of reliable operation with minimum maintenance. They incorporate the most robust positioner in the industry. All antenna-mounted electronic components are housed within metal enclosures for shielding. In addition, each system includes an integral, encapsulating radome that protects the antenna and positioner from environmental elements such as wind, rain, ice, snow and ultra violet rays.
User Friendly Operation
The performance of the central receive antennas is complemented by the user-friendly NSI MC5 remote control, which includes many advanced features to simplify and enhance daily operations, including:
- Peak
- Preset
- Spectrum Analyzer Control
- Map
- Automatic Tracking
- Auto Link™
