The KING Jack Model OA8300 is an amplified HDTV antenna designed to enhance television reception in various settings, including RVs and stationary homes. This device aims to provide clear digital TV signals by amplifying incoming broadcasts, ensuring a better viewing experience. Its design focuses on ease of installation and operation, offering multiple mounting options and clear instructions for channel scanning.

The primary function of the KING Jack antenna is to receive over-the-air digital television (DTV) signals and amplify them for display on a television. Unlike traditional antennas, its amplified nature helps in capturing weaker signals, which is particularly beneficial in areas with challenging reception conditions. The antenna requires a 12-volt power supply to operate its internal amplifier, which is typically provided through a power injector. This power injector can be either the one supplied with the KING Jack antenna or an existing power injector already present in an RV setup.

One of the key usage features of the KING Jack antenna is its versatility in mounting. It offers two main installation options: RV Mounting and Pole Mounting. For RVs, the antenna can be mounted to a bat wing style retractable arm using the provided RV Antenna Bracket. This allows for easy deployment and retraction, making it convenient for mobile use. The instructions emphasize proper alignment with existing pole heights to ensure the antenna can fully retract into a stowed position when not in use. For stationary applications, such as homes, the antenna can be attached to a fixed pole using the supplied Pole Mount Bracket. This setup is ideal for permanent installations where the antenna can be rotated to achieve optimal signal reception. It is crucial to note that the pole mount option is specifically for stationary poles and should not be used on a vehicle.

The antenna's operation involves a power injector, which is a critical component for its amplification. When using an existing power injector in an RV, users are instructed to simply replace their old antenna head with the KING Jack antenna head. A red LED light on the bottom of the KING Jack antenna illuminates when 12 volts are present, indicating that the internal amplifier is powered. A significant warning is provided against using both the existing power injector and the KING Jack supplied power injector simultaneously, as this can lead to overheating, injury, or severe damage to the antenna's power supply. This highlights the importance of selecting only one power source for the antenna's amplification.

For installations where no existing power injector is present, the KING Jack antenna comes with its own power injector and power supply. This setup ensures that the antenna receives the necessary 12-volt power for its amplifier. The manual provides clear diagrams illustrating various connection scenarios, including wall plate TV outlets with and without power injectors, and emphasizes the correct way to integrate the KING Jack power injector into the system. The overarching message is to avoid any configuration that results in two power injectors being active in the circuit.

Once installed and powered, the process of scanning for channels is straightforward. For stationary applications, a one-time scan is typically sufficient. However, for mobile applications like RVs, users will need to perform a channel scan each time they change locations. The scanning process involves turning on the TV and the KING Jack antenna power, then performing a channel scan according to the TV or digital TV converter box manufacturer's instructions. To optimize reception, the antenna should be rotated in 90-degree increments, with a channel scan performed after each rotation. Users are advised to keep track of the positions that yield the most channels. After identifying the best reception positions, the antenna should be fine-tuned to achieve the highest signal strength, followed by a final scan.

The KING Jack antenna is a directional antenna, meaning its orientation significantly impacts signal reception. The instructions suggest that one side of the antenna should face the broadcast towers when properly aligned. To further assist in locating TV towers and simplifying the scanning process, an optional KING SureLock Digital TV Signal Finder SL1000 is available. This accessory helps pinpoint the location of local DTV towers, potentially eliminating the need for multiple channel scans.

Maintenance features are also addressed in the manual. A crucial maintenance instruction is to fill the end of the coax cable with supplied dielectric grease before screwing it to the antenna. This helps prevent corrosion and ensures a reliable connection. Users are warned against overtightening the coax cable. If an existing coax connector is corroded or damaged, it should be replaced with a new one. The manual also provides troubleshooting tips for common issues, such as no TV reception. If the red LED on the antenna head is not lit, it indicates a power issue, prompting users to check the power supply and power injector for proper voltage. If the antenna is powered but still not receiving signals, it suggests that the antenna might be pointed in the wrong direction, requiring a re-evaluation of its orientation or the use of the KING SureLock Signal Meter. A stern warning is included: "DO NOT power wash any part of the KING Jack antenna," indicating that the device is not designed to withstand high-pressure water cleaning.

The KING Jack antenna is designed for durability and comes with a one-year parts limited warranty, covering replacement parts for defects. This warranty underscores the manufacturer's commitment to product quality and customer satisfaction. The overall design and operational guidelines aim to provide users with a reliable and effective solution for receiving amplified HDTV signals, whether on the road or at home.
