3. Setup & Installation

Proper installation is crucial for optimal antenna performance and safety. This antenna is designed for mobile use, typically mounted on a vehicle.

3.1 Antenna Assembly

1. Attach the Whip: Carefully screw the detachable stainless steel antenna whip into the antenna base. Ensure it is securely fastened but do not overtighten.
2. Adjusting the Whip (if applicable): Some models may require minor adjustments to the whip length for fine-tuning. Use the provided Allen wrench if set screws are present.

3.2 Mounting on Vehicle

The antenna typically uses a PL259 connector and requires a compatible mobile mount (e.g., magnetic mount, trunk lip mount, fender mount) and coaxial cable (RG58 recommended) to connect to your radio.

• Magnetic Mount: If using a magnetic mount, ensure the vehicle surface is clean and flat for maximum adhesion. Place the magnetic base on a metal surface, such as the vehicle roof or trunk lid.
• Coaxial Cable Connection: Connect the PL259 connector from the antenna's cable to the antenna input on your mobile radio.
• Ground Plane: For optimal performance, especially with magnetic mounts, ensure a good ground plane is available (e.g., the metal roof of your vehicle).

4. Operating Instructions

Once installed, the UAYESOK TC-8900R antenna is ready for use with your compatible mobile radio. Ensure your radio is set to the correct frequency band for the best performance.

• Frequency Selection: Select the desired operating frequency on your mobile radio within the antenna's supported bands (29MHz, 50MHz, 144MHz, 430MHz, 118-124MHz).
• SWR Check: Always perform a Standing Wave Ratio (SWR) check after installation and before transmitting on a new frequency to prevent damage to your radio. An SWR of less than 1.5 is recommended.
• Power Output: The antenna is rated for a maximum power of 100W. Do not exceed this limit.
• Antenna Orientation: For mobile use, the antenna is designed to be vertical. Ensure it is not obstructed by vehicle parts or cargo.

5. Maintenance

Regular maintenance ensures the longevity and performance of your antenna.

• Regular Cleaning: Keep the antenna whip and base clean from dirt, dust, and debris. Use a soft cloth and mild soap if necessary.
• Connection Check: Periodically inspect all connections (whip to base, connector to radio) for tightness and corrosion.
• Magnetic Base Care: If using a magnetic mount, regularly clean the underside of the magnet and the vehicle surface to prevent scratches and maintain strong adhesion.
• Driving Safety: When driving, especially at high speeds or in areas with low clearance (e.g., garages, car washes), consider rotating the bendable part of the antenna 90 degrees to prevent it from folding backward due to wind force. For added security, heat shrink tape or PVC sections can be used to secure the collapsible part.
