The ClearStream 2 (C2) antenna is designed for receiving DTV signals, offering a blend of high performance and user-friendly features for both setup and long-term use. This antenna is particularly noted for its ability to concentrate radiated power effectively, ensuring strong signal reception across a wide range of frequencies.
The primary function of the ClearStream 2 antenna is to capture over-the-air digital television (DTV) signals. It is engineered to provide consistent and high-quality reception, making it suitable for users looking to access free broadcast television channels. The antenna's design focuses on optimizing signal gain and minimizing signal loss, which are critical for clear and stable picture quality.
A key aspect of its functionality is its ability to maintain a nearly uniform gain across the entire DTV spectrum. Unlike some antennas that might boast high peak gain values at specific frequencies, the C2 is designed for broad-spectrum performance. This means that it performs consistently well across all DTV channels, from lower to higher frequencies, without significant drop-offs in signal strength. This uniform gain is a significant advantage, as it ensures that users can reliably receive a wide array of channels without needing to reorient the antenna or compromise on reception quality for certain broadcasts.
The C2 also incorporates a highly efficient design to minimize impedance mismatches, which are a common cause of signal loss. This efficiency is reflected in its very low Voltage Standing Wave Ratio (VSWR), especially at its optimum frequency. A low VSWR indicates that most of the signal received by the antenna is effectively transferred to the connected cable, rather than being reflected back. This translates to a more robust signal reaching the television, contributing to better picture and sound quality.
Furthermore, the antenna is designed with forgiving aiming characteristics. It features a wide beamwidth, typically more than 70 degrees across its main lobe. This broad reception pattern means that the antenna does not require extremely precise aiming to capture signals. Users have more flexibility in positioning the antenna, and it can often receive signals from multiple directions without needing constant adjustment. This is particularly beneficial in areas where broadcast towers are located in different directions. The presence of a powerful secondary rear lobe further enhances its multi-directional reception capabilities, allowing for a single fixed installation to capture signals from various sources.
The ClearStream 2 antenna is designed with ease of use in mind, from its assembly to its installation and ongoing operation.
Assembly: The antenna comes with a straightforward assembly process. The main components include a reflector, a set of tapered loop elements, a 75-ohm transformer (internal), a threaded bolt, and an adjustable mast clamp. The assembly involves aligning the two halves of a separating column and attaching the reflector (grid) to the antenna elements (tapered loops). This is done by threading a supplied bolt through the center of the column and tightening it. The process is intuitive, requiring minimal tools and effort. The supplied bolt is fed through a hole in the U clamp assembly, which is then used to secure the antenna.
Installation: Once assembled, the C2 antenna can be attached to various types of masts or mounts. The adjustable U-bolt clamp is designed to accommodate masts up to 2 inches in diameter, offering versatility in mounting options. The 75-ohm coax connector, which is the standard connection for televisions and tuners, is conveniently located in the center front of the antenna, making it easy to connect the coaxial cable.
Reception Performance: The antenna's design ensures excellent reception performance. Its high efficiency means that a significant portion of the received signal makes it to the cable, minimizing loss. The uniform gain across the DTV spectrum ensures consistent performance across all channels. The wide beamwidth and powerful secondary rear lobe contribute to forgiving aiming characteristics, allowing the antenna to capture signals from multiple directions without requiring precise orientation. This makes it a "set it and forget it" solution for many users, reducing the need for frequent adjustments.
Environmental Considerations: The C2 is built to withstand various outdoor conditions, ensuring durability and reliable performance over time. While the manual does not explicitly detail weather resistance, the robust construction implied by its outdoor installation suggests it is designed to endure typical environmental elements.
The ClearStream 2 antenna is designed for low maintenance, focusing on durability and long-term reliability once installed.
Robust Construction: The components are built to be sturdy, ensuring that the antenna can withstand outdoor exposure. The use of durable materials for the reflector, loop elements, and mounting hardware contributes to its longevity. This robust construction minimizes the need for frequent repairs or replacements due to wear and tear from weather or environmental factors.
Simplified Design: The antenna's design avoids complex moving parts or intricate mechanisms that could be prone to failure. The straightforward assembly and fixed structure mean there are fewer points of potential mechanical breakdown. This simplicity contributes to its reliability and reduces the likelihood of needing maintenance.
Internal Components: The 75-ohm transformer is internal, protecting it from direct exposure to the elements. This internal placement helps to prevent corrosion or damage to this critical component, ensuring consistent signal quality over time.
Adjustable Mast Clamp: The adjustable U-bolt clamp, while primarily an installation feature, also contributes to maintenance by allowing for secure and stable mounting. A securely mounted antenna is less likely to shift or become damaged in high winds, reducing the need for re-adjustment or repair.
General Tips for Longevity: While the antenna itself requires minimal maintenance, the manual provides helpful tips that indirectly contribute to its long-term performance and reduce the need for troubleshooting. These include:
In summary, the ClearStream 2 antenna is engineered for reliable, high-performance DTV reception with a focus on ease of assembly, flexible installation, and minimal ongoing maintenance, making it a practical choice for accessing free over-the-air broadcasts.
