Power Considerations for Safe Use
- SSB Mode: Up to 200W for voice communication, which is beneficial for clear, powerful transmissions on lower HF bands.
- CW Mode: Up to 100W, suitable for modes requiring continuous or digital signal transmission. Monitor SWR and reduce power slightly in extreme heat or for extended operation.
Tips for Optimal Performance
- Radials: Always use radials appropriate for the frequency. More and longer radials improve grounding, especially important on 40 meters.
- Environment: Changes in terrain, moisture, and nearby objects may affect tuning. Periodic checks and adjustments can ensure the best SWR.
- Safety: Keep the setup away from people and RF-sensitive equipment, especially when operating above 10 watts.
This versatile setup enables efficient communication across multiple HF bands, whether for emergency, recreational, or portable operations, making the CHA M-COIL a valuable tool in field-deployable antenna configurations.
