The document is an instruction manual for the Winegard HD7698 and HD8200 High Definition VHF/UHF Antennas. It provides detailed assembly instructions, installation guidelines, and important safety information, particularly regarding lightning protection.
Function Description:
The Winegard HD7698 and HD8200 are high-definition VHF/UHF antennas designed to receive over-the-air television signals. These antennas are intended for outdoor installation, typically mounted on a mast, to capture broadcast signals for television viewing. The design, featuring multiple elements and a corner reflector assembly, is optimized for receiving both Very High Frequency (VHF) and Ultra High Frequency (UHF) signals, ensuring compatibility with a wide range of digital television broadcasts. The manual emphasizes proper assembly and installation to maximize signal reception and ensure the longevity of the device.
Important Technical Specifications (Inferred from manual):
- Antenna Type: High Definition VHF/UHF.
- Models: HD7698 and HD8200.
- Components: The antenna system comprises several key components:
- Front Assembly: Includes various elements that unfold and snap into place.
- Rear Assembly: Also features unfoldable elements and a cartridge housing.
- Corner Reflector Assemblies: Two units that attach to the main boom, with elements that unfold.
- Boom Brace: Provides structural support and stability to the antenna.
- Mast Clamps: Used for mounting the antenna securely to a mast.
- Cartridge Housing: Contains the internal connections and phasing lines for signal processing.
- UHF Phasing Lines: Internal wiring that connects the UHF elements to the cartridge housing.
- Director Elements: Specific elements that are reinstalled during assembly.
- Hardware: Bolts, hex nuts, and U-bolts for assembly and mounting.
- Connectivity: Designed to connect to a 75 ohm coaxial cable via an F-connector. A rubber boot is provided for weather protection at the connection point.
- Lightning Protection: The manual strongly recommends installing a lightning arrestor or 75 ohm coaxial grounding block, with specific guidelines for ground wire type (copper or aluminum, number eight or larger) and spacing (four to six feet apart) for securing the downlead wire to the house. The grounding system should adhere to the National Electrical Code (ANSI/NFPA 70) as illustrated in the "LIGHTNING PROTECTION - Example of Antenna Grounding" diagram.
- Wind Whipping Prevention: The 75 ohm coaxial cable downlead should be secured to the mast with tape or plastic wire ties to prevent damage from wind.
Usage Features:
- High Definition Reception: Capable of receiving high-definition television signals across both VHF and UHF bands.
- Directional Design: The antenna is designed to be pointed towards broadcast stations for optimal signal reception. The manual includes diagrams showing "POINT THIS END TOWARD STATIONS."
- Modular Assembly: The antenna comes in a disassembled state, requiring the user to unfold elements, attach sections, and secure components. This modular design likely aids in shipping and potentially allows for easier replacement of parts if needed.
- Easy Element Unfolding: Elements are designed to unfold and snap into place, simplifying the assembly process. The procedure for unfolding elements is consistent across both HD7698 and HD8200 models.
- Secure Mounting: Utilizes mast clamps and a boom brace to ensure the antenna is securely fastened to a mast, capable of withstanding outdoor conditions.
- Weather Protection: Includes a rubber boot for the coaxial cable connection to protect against environmental elements.
Maintenance Features:
- Durable Construction (Inferred): The use of bolts, hex nuts, and a boom brace suggests a robust design intended for outdoor exposure.
- Installation Warnings: The manual provides critical warnings, such as "Installation of the antennas near power lines is dangerous!" and "Be sure the phasing lines DO NOT touch the metal bracket or the antenna boom," which are essential for safe installation and long-term performance. Adherence to these warnings helps prevent damage to the antenna and ensures user safety.
- Coaxial Cable Management: Recommendations for securing the coaxial cable to the mast help prevent wear and tear, extending the life of the cable and maintaining signal integrity.
- Grounding Importance: Detailed instructions for lightning protection are a key maintenance feature, safeguarding the antenna, connected equipment, and the structure from electrical surges. Regular inspection of the grounding system is implied for continued safety.
- Warranty: A 90-day limited warranty covers defects in materials or workmanship from the date of purchase, provided proof of purchase is presented. This indicates a commitment to product quality and offers recourse for initial manufacturing issues. The warranty explicitly excludes damage from misuse, improper installation, abuse, neglect, accidents, tampering, modifications, usage not in accordance with instructions, or acts of nature (wind, lightning, ice, corrosive environments). This highlights the importance of proper installation and care for antenna longevity.
- Customer Support: The manual provides contact information for product registration (winegard.com/myantenna) and help (help@winegard.com), allowing users to seek assistance for assembly, installation, or troubleshooting.
