Grounding:
Proper grounding is essential for optimal antenna performance and to minimize interference. Ensure your antenna mount has a solid electrical connection to the vehicle's chassis or frame. In some cases, running additional 12-AWG wire grounds may be beneficial to ensure a robust ground connection.
SWR Tuning:
After installation, it is critical to tune the antenna for the lowest Standing Wave Ratio (SWR). This process involves adjusting the insertion depth of the whip into its mounting hole. A low SWR (ideally below 1.5:1 across the band) ensures maximum power transfer from your CB radio to the antenna and prevents damage to your radio. Use an SWR meter or an antenna tuner for accurate adjustment.
Caution: The set screws securing the whip can be soft. Exercise extreme care during the tuning process to avoid stripping the inner hex (allen) slot.
Operating Instructions
Once installed and tuned, the Wilson T5000 antenna is ready for operation with your CB radio.
- Power Handling: The antenna is rated for 5,000 AM and 20,000 SSB Watts ICAS (Intermittent Commercial and Amateur Service) power handling. Ensure your radio's output power does not exceed these limits to prevent antenna damage.
- Frequency Range: The antenna is optimized for the CB radio frequency band (26.965-27.405 MHz).
- Weather Band: The T5000 is weather-band ready, allowing reception of NOAA weather radio broadcasts if your CB radio supports this feature.
- Optimal Performance: For best results, operate your CB radio within its specified power limits and ensure the antenna remains properly tuned.
Maintenance
Regular maintenance will extend the life and performance of your Wilson T5000 antenna.
- Cleaning: Periodically clean the antenna, especially the coil and whip, to remove dirt, grime, and road salt. Use a mild soap and water solution, then rinse thoroughly.
- Inspection: Regularly inspect the antenna for any signs of wear, damage, or loose connections. Check the mounting hardware and coaxial cable for integrity.
- Protection: The high-impact Mobay thermoplastic protects the antenna in various weather conditions. However, avoid physical impacts, such as hitting tree limbs, as this can cause cracks or breaks in the load coil housing.
- Storage: The removable coil design allows for safe storage and makes it easier to pull into garages or low-clearance areas. When storing the antenna for extended periods, ensure it is clean and dry.
Troubleshooting
If you experience issues with your antenna, consider the following troubleshooting steps:
- High SWR Readings:
- Re-check SWR tuning by adjusting the whip's insertion depth.
- Verify proper grounding of the antenna mount to the vehicle chassis.
- Inspect the coaxial cable for kinks, damage, or faulty connectors.
- Ensure the antenna is not too close to other metal objects on the vehicle that could interfere with its radiation pattern.
- Poor Reception/Transmission:
- Confirm low SWR. High SWR can significantly reduce performance.
- Check all connections between the antenna, coaxial cable, and CB radio.
- Ensure the antenna is mounted in a clear, unobstructed location.
- Loose or Damaged Plastic Housing:
- If the outer plastic housing turns while tightening the antenna, it may need to be re-glued. Handle gently during installation.
- Physical damage from impacts (e.g., tree limbs) can crack the housing. While the Mobay thermoplastic is durable, extreme force can cause damage.
