Key Features:

  • Wide Frequency Range: Operates from 1.8 MHz to 36 MHz (160-meter to 8-meter bands).
  • High Power Handling: Supports up to 120W maximum input power.
  • Durable Construction: Made from high-quality stainless steel for longevity.
  • Standard Connector: Equipped with a PL259 (UHF-Male) connector for broad compatibility.
  • Omni-directional Radiation: Provides uniform signal coverage in all directions.
  • Direct Ground Protection: Built-in lighting protection for enhanced safety.

4. Setup and Installation

Proper installation is crucial for optimal performance and safety.

  1. Unpack Components: Carefully remove all parts from the packaging. Verify that you have the antenna base, the whip sections, and the hex key.
  2. Assemble Antenna:
    • Connect the lower whip section to the antenna base by screwing it in securely.
    • Connect the upper whip section to the lower whip section.
    • Use the provided hex key to tighten the set screws on the mid-section connector to ensure a firm connection and proper electrical contact. Refer to Figure 3.4 for visual guidance.
  3. Mounting Location: Choose a mounting location on your vehicle that provides a clear, unobstructed view of the sky and is as high as possible. Ensure the mounting surface is sturdy enough to support the antenna's length and weight (approximately 1.7 pounds). Common mounting points include trunk lids, fender mounts, or roof racks.
  4. Secure Mounting: Attach the antenna to your chosen mount (not included) using appropriate hardware. Ensure the antenna is vertically oriented and securely fastened to prevent movement during vehicle operation.
  5. Connect Coaxial Cable: Connect a high-quality 50 Ohm coaxial cable (with a PL259 connector) from your transceiver to the PL259 connector on the base of the antenna. Ensure the connection is tight and secure.
  6. Grounding: Verify that your vehicle's chassis provides a good ground connection for the antenna mount. A proper ground plane is essential for antenna efficiency, especially for mobile installations.
  7. SWR Tuning: After installation, it is highly recommended to check the Standing Wave Ratio (SWR) across the desired operating frequency range using an SWR meter. While the antenna is designed for a wide band, fine-tuning may be necessary for optimal performance on specific frequencies. The antenna is factory-tuned for a VSWR of less than 1.5 across its stated range. Refer to Figure 4.1 for an example SWR chart.

This chart illustrates the antenna's SWR performance, showing a low SWR (below 1.5) across the 1.8 MHz to 36 MHz frequency range, indicating efficient power transfer.

5. Operating Instructions

Once the HYSHIKRA TC-B2M antenna is properly installed and tuned, you can begin operating your mobile radio transceiver.

  • Transceiver Compatibility: This antenna is compatible with Yaesu, Motorola, Midland, Icom, and other mobile transceivers designed to operate within the 1.8 MHz to 36 MHz frequency range.
  • Frequency Selection: Select your desired operating frequency on your transceiver. The wideband nature of this antenna allows for operation across multiple bands without requiring manual tuning for each frequency, provided the SWR is acceptable.
  • Power Output: Ensure your transceiver's power output does not exceed the antenna's 120W maximum power rating. Operating above this limit can lead to antenna damage and poor transmission.
  • Monitor SWR: Periodically check your SWR, especially when changing operating frequencies significantly, to ensure optimal performance and prevent damage to your transceiver.
  • Transmission: Transmit as per your radio's instructions. The antenna's omni-directional radiation pattern ensures signal propagation in all directions.

6. Maintenance

The HYSHIKRA TC-B2M antenna is designed for durability and requires minimal maintenance.

  • Regular Inspection: Periodically inspect the antenna for any signs of physical damage, corrosion, or loose connections. Pay close attention to the base connector and the whip sections.
  • Cleaning: Clean the antenna with a soft, damp cloth to remove dirt, dust, or road grime. Avoid using abrasive cleaners or solvents that could damage the finish.
  • Connector Care: Ensure the PL259 connector remains clean and free of corrosion. A small amount of dielectric grease can be applied to the connector threads to prevent moisture ingress and corrosion.
  • Tighten Connections: Re-tighten any screws or connections that may have loosened over time due to vibrations, especially the hex key tightened sections.
