5. Installation

1. Identify Connector Type: Ensure your radio has an SMA-Male connector to properly mate with the antenna's SMA-Female connector.
2. Align Antenna: Carefully align the antenna's connector with the radio's antenna port.
3. Screw On: Gently screw the antenna onto the radio's port in a clockwise direction. Do not overtighten, as this can damage both the antenna and the radio's connector. Tighten until snug.
4. Verify Connection: Ensure the antenna is securely attached before operating the radio. A loose connection can result in poor performance or damage.

6. Operating Guidelines

Once installed, the TD-771 antenna operates passively to enhance your radio's signal. Follow these guidelines for optimal performance:

• Vertical Orientation: For best results, operate your radio with the antenna in a vertical position.
• Clear Line of Sight: Maximize range by operating in areas with a clear line of sight to other radios or repeaters. Obstructions like buildings and dense foliage can reduce signal effectiveness.
• Avoid Obstruction: Do not cover the antenna with your hand or other objects during transmission, as this can degrade signal quality.
• Power Limits: Do not exceed the antenna's maximum power rating of 10 Watts to prevent damage.

7. Care and Maintenance

Proper care will ensure the longevity and performance of your TD-771 antenna:

• Regular Cleaning: Wipe the antenna with a soft, dry cloth to remove dust and dirt. Avoid harsh chemicals.
• Inspect Connector: Periodically check the SMA-Female connector for any signs of corrosion or damage.
• Avoid Extreme Bending: While the antenna is flexible, avoid excessive or sharp bending that could damage the internal elements.
• Storage: When not in use, store the antenna in a clean, dry place away from direct sunlight and extreme temperatures.

8. Troubleshooting

If you experience issues with your TD-771 antenna, consider the following:

• Poor Signal Quality:
  • Ensure the antenna is securely connected to the radio.
  • Verify the antenna is oriented vertically.
  • Check for obstructions between your radio and the receiving station.
  • Confirm your radio is set to the correct frequency band (VHF or UHF).
• Antenna Not Attaching Properly:
  • Ensure your radio has an SMA-Male connector. The TD-771 uses an SMA-Female connector.
  • Inspect both the antenna and radio connectors for damage or debris.
• Reduced Range:
  • Environmental factors (terrain, buildings) can significantly impact range.
  • Ensure your radio's power output is set appropriately for the desired range.
